Come along with Eric O. and Ivan T. from "Pine Hollow Auto Diagnostics" as we have a look at this 2002 Buick LeSabre 3.8 Series II that was towed in from Buffalo, NY. The car is only running on two cylinders with a P0300 and we need to figure out why. We also make a phone call to a mutual friend Keith D. Owner of "New Level Auto" and we learn a lot along the way as Ivan shares some of his scope captures from a recent case study he did. Enjoy!

Just wanted to give you guys a huge thanks. My wife's buick had the very same problem, I threw a few parts at her with no luck. I came across your video by chance. The car had been sitting for a month, and I was about to give up and bring her to the stealership. I did the exact trouble shooting you guys did and replaced the ICM, and she runs like new. Also did plugs and wires keep up the good work, and again you guys rock!!!!! Thanks.

Good video, showing how to properly diagnose using a multichannel scope to trace 3800 ignition woes without resorting to the shotgun replacement method. Nice to know there are some techs out here who still do it right! I worked on the 3800 series 1 equipped GM's which were new at the time, around 1986. That is when I was a young buck tech out of school working for Anderson Buick Oldsmobile Pontiac in Baltimore, fresh out of Lincoln Tech. As I recall some of these GM port fuel cars will disable the coil pack(s) on the cylinders that detect the active misfire(s). This would kill both cylinders fired by that particular coil The unused waste spark fires simultaneously on the companion cylinder's exhaust stroke. In other words, both coil secondary terminals fire at the same time; the cylinder to be fired on TDC compression. The other cylinder opposing it in the firing order fires as well. Sometimes to get the PCM to fire the coil on a misfiring cylinder with a code set for that cylinder, clearing the PCM and erase the engine codes is required. This allows the quad driver(s) in the PCM to ground that coil, enabling the PCM to control each of the 3 coils. For the 3 pairs of module terminals provided, one terminal provides 12vdc at all times, either in KOEO or KOER, the same scenario with the 12vdc fuel injectors. Cam and crank sensors, along with MAP-Baro, MAF, ECM and IAT control timing and injector pulse. Engine cold, this runs the engine off the IAC-engine RPM, base ignition timing and injector pulse / fuel tables. Once at normal operating temperature, the PCM uses adaptive strategy which is then altered based on the sensor inputs. A Quad Driver is a fancy name for transistors that control the ground to various 12vdc devices controlled by the PCM-ECM, whether a simple off-on state, or pulse width modulated. Another popular stumbling point is making sure the right number cylinders are on the correct coil towers, since you can swap them among all 3 positions and mix up the numbers on top of the coil, or in the case of new coils, there are no numbers on the replacement coils. Once everything is running and codes are cleared you will also need to go in with the scan tool and set the RPM rev limiter. Typically on these engines, unless the module was new-ish, at the dealer we would recommend replacing the coil module as well. Running bad coils, multiple misfires, or shorted ignition secondary would stress the module and cause it to fail shortly after a a coil was replaced. Better to err on the side of caution and prevent a possible come back than have the car die shortly after the customer picks it up thinking everything was good. On the 1st generation 3800's the coils were all one. The coil brick as we called it came as a set of 3 coils in one, with 3 pairs of wired terminals that plug into the coil brick. These were even more notorious in failing for no real reason, and simply running with one plug wire accidentally disconnected could blow the coil and module.

@neutrodyne
@neutrodyne 3 года назад
A few notes. First thanks to South Main Auto for providing us with this video. I'll have to say that this is my favorite youtube Auto repair channel. Having said that I would not recommend pulling coils out with the engine running. This could possibly damage the ICM from a thing called kick-back reactance. I would also not recommend removing the plug wires from the coil towers to see if there is a spark across the gap. This allows excessive high-voltage that could cause an internal short to the coil. Next, I would highly recommend cleaning the mounting bracket the ICM mounts on and putting in some heatsink compound between it and the ICM. Heat is an enemy to solid-state devices and removing the heat from the ICM can increase its life. Last, what we have in this situation is one of the coil driver transistors was bad in addition to the logic circuit being bad in the ICM. This caused some very confusing and unusual test results. Thanks again for sharing this.

Eric, not sure whether or not you're going to see this, but I'll try anyway. Measuring the DC resistance of the coil may not always tell you the entire story. The only way to really know for sure if you have a bad coil is to measure its inductance, and the only way to do that is to use an LCR meter. The inductance of the coil is determined by the size of air gap in its core, and its number of turns around the core. As coils get damaged, often times turns short to each other, or the core cracks, essentially making the air gap larger, both conditions resulting in decreased inductance. A BK precision model 879B would be suitable for measuring that. At $300 it's not cheap, but it's worth the price of admission because it'll pay for itself in unnecessarily replaced ignition coils. Shooting from the hip, a typical good coil probably measures in the order of hundreds of micro-henries on the primary side, and probably thousands of micro-henries on the secondary side. If you measure a few nano-henries, the coil is most likely no good. Hope this information helps someone if not Eric O.

@Kenny Coultrap The 3800 is one of the best engines ever built, right up there with a coyote, and K series. Don't knock it just because the damn thing absolutely refuses to give up even when you disable 3/4 of the engine. PS: Full disclosure, YES I'm a fanboy. Own an 05 Impala 3.8 9c1. Cops beat the hell out of it, I bought the car with the title at 166k. Odometer read upper 80s. It's now at 175K and besides a crank no start two days ago (Oddly enough the ICM went) it runs like a freaking champ. But then again, considering it's my work vehicle, I maintain the ever living shit out of it. As I run it 200+ miles a day. Now, I will say, thanks to the insane mileage on it (I'm guessing with the discrepancy probably at or above the 300K true mileage) everything besides the engine and transmission has broke on it. But you know what? She keeps kicking for me, I'll keep treating her right. Hell, when the transmission goes, I'll get it rebuilt. Love this car and the only way I'll ever junk it, is if I buy another one with lower mileage.

@josephwash109
@josephwash109 7 лет назад
Possibly the reason the coils sparked during cranking and not when the engine was running is because this ignition system is the bypass type. During cranking and at low engine speeds, the PCM does not apply 5 volts to the ignition control timing signal circuit (Pin B on the ignition module). At that time, the ICM controls the saturation time of the coil windings. Once the engine starts and the PCM starts receiving crankshaft sensor pulses, it applies 5 volts to the IC timing signal circuit and the PCM controls the dwell and spark timing. It's almost a primitive communications line between these two modules. I would figure the dwell is longer from the ICM to make sure the coils saturate well to help the engine start faster.The only reason why this engine is probably able to run on two cylinders is because of its unique firing order (1-6-5-4-3-2) and the fact that they have an internal balance shaft to help the engine run smoothly.I had the GM service manual handy, and decided to throw my two cents in. I couldn't find the primary coil resistance spec, but if I remember right, it's 0.3-0.8 ohms.I'm definitely going to subscribe to Keith's channel. I want to see the crazy stuff too!

You guys are excellent techs.!!! It is sooooo refreshing to see you guys do proper diagnostics on this 3.8L!! This is how techs are supposed to be able to do things!! I have worked in shops and seen soooo many shade tree mechanics throw parts at the car to try to diagnose the problem, then the owner of the car ends up buying several new parts that they didn't need!!! That type of tech is who causes the rest of us REAL TECHS to get bad names!! BUT, like I tell the customer, I promise them UP FRONT that I will correctly diagnose the problem from the start, and I will only have the purchase the exact part the car needs to fix it!! I always tell people, almost anybody can change car parts!! Usually if a person can figure out how to get the part off they can usually get it back on the car!! But it takes a real tech to do a correct diagnostic the first time, and be able to tell the customer what the real issue is with their car, and not replace parts until they find the problem!!! So great job guys!!! It was nice to watch your video and use your video to show people how correct diagnostics are done!! It's hard for me to personally show people correct diagnostics procedures, because I can't take people to work with me!! So thank you guys!! Great job!!!

You missed the part where techs today have to understand these systems even more than the engineers that designed them.. while being paid a small fraction of their salary.. if you want mechanics to be engineers, then the industry is going to have to start paying them as such.. the average mechanic barely makes more money than an 18 year old at Mcdonald's

When I junked the car for him in 2014 he had 483,000 miles on the car and on the original motor and tranny. The 3.8 motors are great if you do the common problems.

As an owner of one of these cars with the Buick V6's i will say that if your a do it yourselfer its always great to have a spare coil, and module on hand just in case something catastrophic happens on the road. One thing i learned is if you are ever playing around with the radiator be sure to cover up the coil packs because they will possibly misfire if antifreeze is splashed on them.

If they plan to keep it i would have replaced the plugs and wires 3 coils and the ignition module with delco components. Just keeps from having comebacks and smother running car with better fuel mileage. I also check the intake for leaking and smell for bad fuel pressure regulator for a bad diaphragm. That seems to fix the biggest problems with the engine. I am learning a lot from all the videos and appreciate the time you spend. God Bless.

I love how you guys joke about that stuff because it's something we see every day and can relate to. Customer comes in with a print out from AutoZone/Advance and says they need an O2 sensor. I do my damnedest to tell them that it doesn't mean they need an O2 sensor and it's probably something else and they should pay for a diagnostic. Some do but there is always the knuckle head that will refuse and demand that you change the oxygen sensor because they are too smart to be tricked into paying for a proper diagnosis. Depending on their attitude they might get a free check to educate them and gain a customer or they might get a waiver saying that they want it changed and we didn't recommend it. Either way we usually gain a customer because they come back with their head down wanting to pay for a diagnostic. These parts stores with free code scans and uneducated shops are bad for our industry and make it even harder for us shops out there that do things the right way.
@44R0Ndin
@44R0Ndin 6 лет назад
IMO the part stores that have free code scans are more and more a necessity for anyone trying to repair their own vehicle. Some of those people who try to fix their own cars become actual mechanics. Some of those eventually specialize in vehicle diagnostics. So before you say those free code scans are bad for the industry, think about where the new techs are coming from. Uneducated shops ARE bad for the industry. There needs to be more and more affordable education on the complex systems modern vehicles have inside them. Those unwilling to learn how the new stuff works will never prosper. My dad's been in the auto repair business for about 40 years now, and he still goes to seminars and classes to stay current on new technology. He doesn't have a scope or a very modern scan tool, but he still manages to replace the right part (and only the right part) 99% of the time. No "parts cannon" here. Meanwhile I'm here fixing lawnmowers and other outdoor power equipment. The only "scan tools" I have are my eyes, ears, and nose. I make more mistakes than my Dad does, but I still fix 100% of the things that get brought in to my bay. Lots of carburetor rebuilding in my line of work.

Your shop maybe legit but not all shops are. There are shops not all but some out there that get over on customers any chance they get. Claiming they can get the part for you at a discounted price but the customer doesn't reap the benefit of the cheap part because the shop feels justified in raising the labor cost because the part was cheap. Its worse when a shop tells you that any part bought outside the shop voids your warranty on any repair they do which is total bs.i rarely have these issues because I know my shit and bring my car to reputable shops for diagnosis or a job I simply don't have time or the tools for.

The problem is that the shops charge for diagnostics $120 and they don't even tell you what the problem is because they couldn't find it. I once was had a problem with my car, and I replace few parts that could be the culprit, but it didn't fix the problem. Eventually after few months of looking for the cause, I said Ok I will spend $120 for diagnostics. Guess what, they were looking, and they didn't find anything, but because of that they charged me "only" $60. Well, that put me in the sqaure one again. I eventually figured it out myself after another year of looking. But what I am trying to say is that they will not always tell you what the problem is. If I had to pay $120 every time for diagnostics, I would need to buy a bicycle instead, because my car is breaking and needs new parts every few months.

I would sell the customer the Icm, 3 coils, wires, plugs, and change the oil to protect the repair. you could have a coil secondary voltage leaking into the primary causing icm control and current limiting issues.

First part of the video is a good example of why mechanics (or anyone who owns or runs a business) should always treat every customer right. Customers talk to other people. If a customer had a good experience and felt like they were treated fairly, they will tell their friends, family, and so forth. More customers, more profits, and loyalty. I've been screwed over by so many mechanics. Screw me over once, I'm done with you and I will tell others if need be. I've taken some time to educate myself on diagnosing vehicle issues. I can't diagnose everything, but I can get a pretty good idea of what's wrong before I take it to someone. Right now I'm between mechanics because the last one never seemed to want to work on the vehicle and I'm a bit "gun shy". There's another mechanic I'll probably try because I've heard others talk good about him and he seems like a nice guy.
