The Influenzo, my Ferrari 308 has had lots of issues but not being able to turn right without bogging down was one of the most elusive and apparently something all Ferrari 308's with carbs do.. not anymore!!
Congratulations on finding the problem and compliments on the clever method you employed to do it. Too many mechanics these days are nothing more than parts changers and your methodical diagnostic approach should be commended. Well done.
Did you notify Tyrell of your coil discovery ? What is flawed in modern coils, to not work properly with old Italian engine designs, when changing direction, in your case, turning right ? There must be happening something like a disconnect somehow due to a pulling or pushing, which seems odd, unless there is rather a ECU print plate issue, whenever modern coils are being used. I saw something similar with another type Ferarri. That was a guy who bought cheap supercars with money provided by his step mom.
m.ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-tEBe6QWTk9U.html samrac - similar Ferarri, know for ECU issues, that may thus be caused when hooking up new electric engine components
Same here i sent him a message on Instagram saying i had the same issue with an old mini with horizontally mounted cool cutting out on cornering tot one side...
The folks that thumbed this video down have never owned a "vintage" car. The joy of persisting with a series of diagnoses to get to the core of issues impacting the performance of your car is hard to describe. Great to see you smiling pal! Car is looking, sounding and driving fantastic.
That is fantastic mate. Seeing the bank cut out must have been such a relief to actually know where to find the problem. Love the perseverance and glad it paid off.
Mate, you have no idea how happy I was when I saw that bank cut out. I was absolutely dreading having to take the carbs apart again.. with no idea of hear might be wrong!!
Never would've thought it'd be the coil especially since they were new & Bosch. "They don't make them like they used to" Never been more true. Congrats 👍
A lot of Bosch stuff has gone down the toilet. Always had as much Bosch as possible in the past. Washer & dryer lasted 25yrs plus. Then, 2 Bosch leccy hedge trimmers, 2 yrs in & the eccentric mechanism in both that gives the blades their reciprocating action died. Bosch lawnmower cuts great, but the height adjuster is truly a POS after only 2 yrs. Jammed & the plastic handle broke. New Bosch washing machine is as good as the old one (both need a few extra kettles of water due to this water saving rubbish all manufacturers are obsessed with - just stop Nestlé hogging it all), but the Condenser Tumble dryer is a POS. The plastic door handle snapped & forums prove it's a common issue. The fluff filter doesn't work at all. The condenser needs regular cleaning. There's a hidden flap where access to a float sensor gets blocked too. No info in manuals, Bosch website etc. Frustrated RU-vidr highlighted it. Was on the verge of binning the dryer after 3 years till RU-vidr solved the problem, but it regularly needs an arm up the outlet & the condenser cleaning out. Bosch's solution on later models? A gasket round the filter? A friend's Hotpoint NEVER needs clearing (4 adults in rented house. Lots of use. No. A 2nd filter AROUND the 1st filter With a F##koff great big plastic moulding. Not a simple rectangular seal? 😅😂🤣 German engineering? German planned obsolescence & German parts sales more like. The dual filter is their way of ensuring they don't get a class action law suit for "not fit for purpose", maybe? I avoid Bosch these days...
Nice one Jack! Althought I still don't understand WHY corners affected the coil; loose component inside?? It defies logic. Anyway, so glad you finally fixed 'right corners' with an original part and loved your reactions to the footage on first viewing.
Been watching you for months. Don’t know why I hadn’t subscribed. Just have. Congrats on finding the problem and please keep your videos coming. I’ve practically given up on watching telly. Your videos are both entertaining and very well edited.
This was happening to me on my Alfa. I had replaced the coil a few years ago for a hot start issue, solved that, then had this annoying issue where the car would cut out going around corners. It ended up getting worse, and engine heat made it worse. I watched a 'Heidi and Franny' episode where they measured the leads on their Porsche's coil, and did that to mine. It was way out of tolerance on the primary leads. Then I discovered that THE AUTOPARTS STORE GAVE ME A NON ELECTRONIC IGNITION COIL. I looked up the tolerances of the original coil, and bought an MSD high output coil. Problem solved. The original coil was Bosch and NLA, and the 'next best thing' Bosch had was out of stock in all of the Alfa parts houses.
Logic: old coil,no bogging:new coil, bogging. You gave yourself a lot of hard times and worry by straying from the obvious but I am delighted for you all the same. Cheers
I bought a set of eight of those plug testers a few years ago from Halford's and still remain in their blister packs. I would never have considered a new coil to be at fault particularly of German manufacture. Obviously the makers have an issue with quality control. Glad to see you have finally solved the most irritating of problems.
Love the determination and meticulous and inventive ways you've gone about diagnosing this fault. Who would have thought. Hope you get something back from Heir Bosche 🙂
If it was me, I'd put the 'iffy' Bosch coil back on and see if the issue returns. If it does return there is no question that it's the coil at fault rather than an iffy connection to/from the coil that got fixed when swapping coils...
YEEEEYYYY, i dont think i have ever been so happy to see a "fix" on youtube before :) so so pleased you have fixed that issue, onwards and upwards...fantastic, brilliant, amazing. :)
I bought a 500 dollar mercedes 300se. it had a straight six that wouldnt run right untill higher rpms.... the k-jetronic injection system can be a problem to adjust without the proper tools. it ran great after it was adjusted properly. if not for all of the hassels I had gone through with a 77' 924 back in the day I would have walked away from an opportunity to actually profit on a car.... should have kept it. that was a nice car.
Great video, I work in diagnostics (not cars) and the feeling you get when you solve a tricky problem and find the little bugger that's the culprit is ace.
Congratulations! Perseverance pays off. I've said it before and I'll say it again. Once you sort out the other bits, do not sell it!! It would be impossible for anyone else to appreciate it as much as you.
I feel like we all felt the excitement with you and the pain in the past. I’m sure we can all relate to situations like this and it’s such a joy to solve. If I were you I would have stayed up all night driving doing right hand turns. Lol. Great work and thanks for never giving up and documenting it for us.
One of those marvellous DEEP JOY moments which makes working on an old car with problems so very rewarding when you suss out something by yourself. Been there, done that more than a few times and will never tire of that experience.
Awesome, great job. Regular coils are usually isolated by a coating of plastic and sometimes it can ground out, but it is strange that it only occurred on right turns. They make higher performance coils that are oil isolated, maybe something to consider in the future. Coils are usually just rated by size and resistance, so you can use many different kinds and experiment. I went away from Bosch blue's and use oil filled coils now, but I do sometimes use Lucas coils. It all comes from China mostly.
Well done! That would've ben the last thing that I suspected. A coil is just two windings with a core and an oil bath for heat transfer. It's really rare to have an internal loose connection.
I'd wondered about some sort of loose component in the coil. Got to be the strangest fault I've ever come across. Could it be the movement of the oil somehow affecting the voltage generation. 🤷♂️
See I'm thinking the oil sloshing around may be the cause. Maybe a bit of swarf in the oil moves to the back of the coil on RH turns shorts out something? Defo weird
" I can do right handers"...amazing...thanks for the clever editing that made it look like we knew ahead of you...sweet trick......any chance of finding out why the coil tripped up turning right?
The oil useage might be caused by unburnt fuel washing down the bores when the coil wasn't firing. This could cause dilution/thinning out the oil which in turn could cause higher oil consumption. As for Bosch coils, they were OEM fitment on older bmw's and older Volvo's of which i still own 1. I have never ever had problems with a Bosch coil. So it must have been a freak part. BTW you can actually MEASURE if a coil is good or bad by measuring the resistance (Ohm's) on the primary and secondary windings. I bet that Bosch coil is actually OK but there might have been an issue with the 12V/ground connections to the coil.
Then explain the old Marelli coil working fine Fairly confident he swapped back & forth just to check it was the Bosch, in case it was a loose connection. Doubt he's too dim to not have checked.... 🤦
Finding this kind of issues is so satisfying, my e46 was dying randomly while driving, it drove me crazy, until I've found that the engine plastic cover was rubbing on the fuel pressure sensor wires and they were shorting
Need to complete the ABA test ie the Bosch coil is A and the Marelli coil is B. Just be sure that is the coil and not the disturbance to the wires caused by changing the coil, that fixed the issue. Else there is a risk of the fault returning, when the wires settle back to their old positions.
Inside the coil is windings and at the factory when a spool of wire has ended a new spool is used and the wires are connected by way of a knot and if this comes undone then this fault will appear!
@@giuseppegiacomoni7058 Good info. I take it where the knot is made the insulation is removed? They do the same when making co-axial cable, the machine operators are constantly knotting wires together.
Are these kind of coils oil filled for insulation and cooling? I seem to recall someone saying years ago (unless i'm thinking of something else). If this is the case and the oil level was low, if when the oil moved to one side and leaves air i.e less insulation it could break down / track /arch. Just a thought. I could be totally wrong....
That's really odd, you'd think that the car would pop and bang from the exhaust as the unburnt fuel is ignited when the coil cut in again, i'd love to know why or how the coil would cut out like that. Nice detective work !
Really pleased you sorted that (and feeling a little smug as one of the guys saying it sounded electrical from the off 😇) . Brilliantly imaginative setup with the spark indicators and cameras - never would have thought of doing that and it was so clear 👍 The influenzo is getting better and better in your care 😊
Reminds me of a time I had an old Peugeot diesel. It was always a first crank starter until one day a glow plug went down. Bought a new pack of plugs and installed them all and next morning, it was still rough. Top and tail was I assumed it to be an engine fault and left it for about a year. Until one day, I saw my arse and decided to have another look and wouldn't you know it? A faulty plug. It had obviously never warmed. One new plug later and it was back to behaving itself impeccably. Ironically, a Bosch part was my saviour in this case 😂. Great video and a solid lesson for us all. Cheers, pal :)
In 1979, I got told by the late Jeff Carter from Australia that the DCNF'S were not designed for transverse apps, so you have to adjust the float height working range ( static and drop) like Austin Rover eventually did in the R series Maestro 1600 twin carb. The Noid lights....great idea. Nice Sluth Work Holmes! The flat plane crank mean the Marelli distributer problems can be seem Pronto!
Brilliant! I’m so happy for you! I don’t think there would have been a better reason for it not working than a brand new German part being to blame and an old original Italian part being the fix. Hilarious.
Fantastic! Great job figuring it out. It is so good when you can figure out and fix something. It makes you more positive when tackling the rest of the issues. But with this Italian mule I am sure the highs and lows will continue! 8^)
This is a great example of a calm approach supported by a logic, systemic thought process. Very well done ! Agree with the comments below that this channel is a step up from "parts swapping" channels.
I'm still somewhat skeptical that it was the coil, more likely a wiring connection issue in my opinion. Perhaps you could put it back in again and retest just to verify?
I'm thinking the oil inside sloshing around maybe causing the primary/secondry windings to overheat perhaps? Insufficient oil. I'm sure the coil amplifier and coil would be a matched pair. So fitting a replacement might not give the coil enough power for a full spark. (Like 85% spark instead of 100%) Strange how it wouldn't work on RH corners?
And if it is the coil, and some kind of sloshing problem, then it should be possible to reinstall, get it to fail on right turns as before, then rotate the coil 180 degrees and get it to fail on left turns. (assuming mounted vertically.)
My mentor once told me this: "All carb problems are ignition, all ignition problems are carbs." Ok, maybe more than once! He didn't mean it literally but I had just learned the hard way that very thing. And I see that you have as well! Congrats! I know that more mayhem is to come but this was a great victory!!
There are Bosch coils and there are "Bosch" coils. Ask the VW/Porsche crowd. Spain/Mexico/Brazil/a back street in Turkey. Take your pick. I don't think any are made in Germany now?
Sending a massive American high five. Ow your face when you realised, like a kid getting the present he’s been wanting all year at Christmas. Ow hell yeah keep going things come in 3s
Fantastic, you’ve cracked it! 😀 So pleased for you I’m grinning from ear to ear too Jack. Watched the whole series of these and so glad you’ve managed to find a fix. You deserve a beer now.
Come on Jack - I mean, this is hardly surprising is it? Everyone knows that German car parts are trash and old Italian stuff is really reliable. No... hang on... wait... (I'd love to know exactly what is wrong with that new coil though, and huge congrats for fixing the issue)
Bloody Well Done Jack!!! Never in a Million Years would I think that this ongoing issue was due to The New Bosch Coil... I'm seriously over the Moon with this news and BTW... I absolutely Love the Christmas Lights that go above the Spark Plugs. Awesome work, Brilliant deduction! The World is Yours my friend and Congratulations Jack! ❤🙏❤
Brilliant, Number 27! (Applauding) Bravo! Congratulations! I've heard in the past about new parts not working at all. That can happen to the best of them (mechanics). That's why we need to learn how to test all new parts before installing. Yet, I still don't know how to do that. Maybe that's something you could make a video about. I'm already subscribed because I look forward to see you getting Influenzo sorted & enjoying the drive. Two Thumbs Up!
Yes! I love the persistence and ingenuity in diagnosing this problem and the positive outcome...but I don't understand how a right turn could cause an intermittent fault.
Hahaha I loved your reaction because I've been there too and when you actually diagnose and fix the issue... it's like Christmas, your birthday and getting a big raise and bonus all at once. Well done!
Glad you have it sorted Jack. Not sure if you plan to try and get a refund or a replacement for the coil, if not it would be interesting to cut the coil open to see if you can locate the fault. Must be a bad internal connection or short in the windings perhaps. I have been following your saga with the car, I thought ultimately it would be an electrical issue, the way it was cutting out and recovering so instantly, I just didn't think a fuel supply issue would behave like that. Anyway great job Jack, ingenious use of the cameras and spark indicators. I'm really pleased for you.
Finding a simple and definitive solution to this type of issue is such a big win. I am so reluctant to fit non Porsche parts to my cars now as several have let me down, & Stuttgart never has..
Fantastic news Jack. Well done. I was so badly willing the coil to fix your right turn misfire issue, and I was with the previous attempted fixes too. What a triumph, and like you said, not what you would have imagined to be the issue when turning right at all. The Influenzo sounds awesome. Hope you can get some serious enjoyment from it now. By god do you deserve it 👌 Keep the great and interesting videos coming. They’re really enjoyable, and sometimes frustrating (but in a good way) 👍
You're happy, you're happy Jack, I'm ecstatic, I get to keep my left nut, because I previously bet it on the problem with "Influenzo" being electric. Years ago my Mum's old Mini had a "shorting coil", the engine "stuttered" on big bumps, took ages to find. Great result Jack, and great entertainment...
So pleased for you. I’ve just had a similar problem with my Jaguar XJS V12 with a misfire on one bank of cylinders and it’s so satisfying when you find the issue which was also a faulty coil for me too. We done. 👍
Great idea on troubleshooting the problem. My experience on my Alfa Milano Verde is the German parts are the weak link. Sad but true. I fixed my oil consumption problem by running some ATF through the motor before an oil change, 1 quart for 50-70 miles keeping the rev's low. It worked great!
I have years of experience diagnosing electrical issues on MGBs, Triumphs, and other cars. I never would have suspected an intermittent coil based on which way you turn the car. Congratulations on figuring that one out.
