I have 06 Chevy impala lt 3.5 and have a P0301 code and have changed everything (spark plugs, wires, coil pack, MAF sensor, and fuel injectors) still reading same code P0301 - blinking engine light and goes away when I drive. Any suggestions on what else it could be?
Couldn't help seeing the irony of him throwing the wad of wasted money and then picking it up with a arm full of tattoos. Now let me watch the rest of his video :)
My V.W. shows misfires on 2 and 4. Bought new plugs and coils cleared codes, came back 2 and 4. Changed coils to Bosch o.e.m. cleared codes, still 2 and 4. Compression test good, plugs and coils look good. I'm out of ideas.
You need to check the Injectors. They might have got clogged. Just put a bottle of Injector cleaner in a full tank and drive the car or let the engine run idle
Hey, I got a P0300 code on my 2009 Infiniti G37. my mechanic told me to install new spark plugs and which did (NGK iridium the best I could buy). AFter a week same P0300 code came back. Would i need to change all coils? because my code does not pin point like this video which cylinder is misfiring. Any help would be appreciated.
I had an intermittent misfire on my '98 LeSabre 3800 engine under acceleration. No codes. Idled fine, ran down the road fine. Decided to look at the plugs. #4 plug had a crack along the porcelain portion of the plug causing occasional missfires. Didn't find the problem until I physically removed and inspected the plugs. So yes, it could be a plug problem.
2020 Jeep wrangler 54,000 Multiple Missfire took it in to the dealer blamed. Me for slush in engine so I took it home and changed spark plugs and coil and still acting up jeep told me I need a New engine now it sits in my Driveway I change the oil every 3,000 miles but since I never used there services they gave me the Finger
I've just been told to scrap my 2014 vauxhall Agila, 62k miles , had reg services , cylinder 2 missfire , they told me plugs and new coil pack still ain't cured it and they've gone on to say the engine needs stripping etc etc , I'm devvoed
Is it still running ok apart from that misfire? Vauxhalls are well known for this misfire. A lot of the times it’s the damn EGR valve especially since this crap E10 fuel. I’ve changed 3 on my Zafira since this stuff has been forced on us. Try giving it a clean or get another one. They’re simple to swap over, 2 bolts but they are a Torx head so be careful they’re not rusted up. For the sake of £20 it’s worth a try. Otherwise run it until it dies. Or then get a new engine. It’ll last much longer than any off these newer cheap, not built to last engines these days. Good luck.
Just subscribed. I assumed with the video being of this quality you already have several thousand subscribers. Looking forward to seeing what else you bring. Thanks!
I love intelligent people ! so many shops just love to replace parts due to lack of proper training .good job you made my morning coffee taste better ..ha !!
So previously the car blew the head gasket and the coolant was escaping into cylinder 2 but that's fixed but I also had a red hot catalytic converter, could this be fuel related
So a p0300 is a random misfire Which is typically caused by something that affects all the cylinders, are there any other codes accompanying the p0300?
misfire but throwing no codes on my 2013 hemi 5.7 it started after i put some oreily brands fuel injector cleaner. matter of fact the drive after using the oreilys fuel injector threw a flashing check engine light while driving. and the misfires are random
Sometimes the codes take a little time to pop up, But I’m personally not a fan of adding those shelf fuel treatments, If I want to service my injector, then I personally take them out and take them to a place who can clean/ flow test them to ensure they are matched and have a proper spray pattern
@@NoNeedGaragewhat if after moving the injector. It doesn’t change? And even after performing compression test ..all cylinder found to be okay….what is next?
@@efivegauthierchryslercanad3066 So a compression test is a bit of a broad test and doesn’t always show a smaller compression leak, a proper leak down test would be better suited We can chat further if you would like, Please email : noneedgarage@gmail.com
@@efivegauthierchryslercanad3066 also another possibility could be the wiring to the specific cylinder, for either the injector or coil, or a possibility even an injector driver in the ecu depending on the car You would need to verify if the plug is actually creating spark, and if the injector is getting a proper pulse signal from the ecu (via a noid light) But as mentioned, email noneedgarage@gmail.com and we can chat further in detail about your issue
Thanks for the input! I’d rather just use brake clean since it evaporates quickly and I don’t have to lay back down in it. Plus it’s literally made to clean brake dust/ fluid. So it’s just easier over all. Thanks again! Subscribe if you haven’t already! :)
@@NoNeedGarage yea right after I hit send, I realized you don’t have a lift and will likely end up laying in water after lol. Brake clean’s main purpose is a degreaser, so being that it’s really bad for your health and major expensive I tend to stay away from it at all costs
