CHEVY COBALT DEAD MISFIRE CHECK ENGINE LIGHT FLASHING DIAGNOSIS

- เผยแพร่เมื่อ 14 ต.ค. 2024
- Welcome back! In today's video we take a look at a 2008 Chevrolet Cobalt with a 2.2l Ecotech engine. The customer complaint is that the check engine light is flashing and the engine has a severe misfire! After replacing the coils and spark plugs we realize that the misfire is more serious than we initially thought. Follow along as I show you how to diagnose an engine with low compression and how we were able to identify a leaking exhaust valve.

My automobile knowledge has never accelerated so much in so little time. I had no idea the amount of diagnostic tools available to us. You have gone above and beyond. I truly hope life is treating you well. Thank you for the knowledge.
Soy Fadi de Siria, vivo en Estados Unidos, trabajé durante dos años como mecánico y ahora tengo un taller. Me gusta ver tu trabajo. Eres inteligente.
Eric, in my opinion, you are one of the two best diagnostic experts on automobiles that are on TH-cam. Every step of your diagnosis is to the point with important information and without a lot of filler (such as how to remove this bolt, or how to remove the spark plug, etc) Each step is quickly stated with all the important information. This coming from a technician that worked in dealerships for over 40 years. I thoroughly enjoy watching your videos and to try figuring out the problem along with you.
As soon as you got into the seat I knew what was the problem, THE STEERING WHEEL COVER!!!!!!!!!!!!!!! 🤣🤣🤣😂😂😂 🤪 🤪 🤪 🤪 🤪
One of my favorite misfire diagnosis I've seen. Great Job.
I love when I go into something and it takes a totally different direction. Makes these jobs fun and keeps things interesting. Nice find!
Erick making compression sounds is priceless 😂cool video to see the valve gap
Fantastic step by step process to find a miss, will be watching for part 2, thanks for posting
Damn, you just got the GOLD MINE if the customer wants to totally repair the car!!! New head possible transmission rebuild, etc, etc!!! 💰💰💰
Educational as usual, thanks Eric, you're a blessing 4 young mechanic like us.
the only channel i imediately click on newly uploaded videos! looking 100% for part 2!
You make doing videos look easy...
It shows your knowledge and skill sets are very well tuned.
Thank you for your inteligable thorough descriptive vids.
God bless
Holy crap!!! I want that GM scan tool to see Lloyd! That is a whole new advantage that I have not seen with my 06 Chevy Cobalt! That scan tool is the most useful tool I have seen in a very long time. Thank you! For your video. Lloyd is in better shape than than this vehicle at this time. He is about to roll over to 200k. I love him so much.
Detailed diagnostic found this video very informational. 👍
You are a great diagnostician Eric. Thanks for the comprehensive video, good editing, no fluff, just solid information.
We appreciate your content Eric
you could have put a rubber glove over exhaust and taped to seal. to demo the air leaking as it would blow up and explode and looking at the valve it was wobbling so the valve stem guide is shot can't wait to see fix keep up the good work Eric
Another great video, I hope you make a video. WHEN fixing the transmission code.
Brilliant diagnosis Eric - really learned a lot. Many thanks
hey i really like your videos,,you explain every step real good,,thanks
Nice diagnostic. Cheers from Brazil, friend.
Terrific diagnosis.
Man, always good vids, good cases and great teacher !!!. Loking foward for the repair.
Thanks Eric,,, much appreciated for all your great teaching and information,,, 🙏👌
Such an awesome video. Definitely looking forward for the second part.
Great video.
Waiting for the continuation of the misfire problem.
thanks.
One of the most educational passionate skilled professional tutorials ever ! Thanks for the great work to teach us .
Thanks Eric for the Knowledge. You tried💪💪💪
You are a great auto repair guy , thanks alot for the valuable informations . KSA
I really love your videos I really learn a lot from them. I have a Question how do you have compressed air on the road what is your setup
Eric, AWESOME content thanks for sharing and doing relative compression from the car battery as u down in the past would be much easer to find low compression as always great information. cheeeeeers
Excellent video. Just wondering if you posted the next video yet with the valve replacement?
Cant wait for part 2!
Very interested to see what you find - looked like the valve was maybe bent, but how did it get bent?
Eric how long did it take and where did you get all this knowledge from? I feel like six months working with you would be like ten years in the field. Just subbed newer tech here.
4:58 It is going to be Cylinder #2, my man! THANK YOU for making videos that aren't ANNOYING or CORNY as well!!! I like.
Well I think once you take care of the engine issues... there may be a good possibility that the transmission issues could correct. Erratic Rpm can disrupt inputs, and include flag false codes. I'm looking forward to seeing the work getting done!
On another note.... other YTers and colleagues and I just got done with the Super Saturday Automotive Training event here in Philly. You NEED to go to one of these events... and Oz I'm sure would be there too.... though he wasn't at this SS, I think he was just at ASTE in NC. You would fit right in! Plus! There's so much knowledge being passed around! Stay safe! Ttys
Fixing the engine will not fix the shift solenoid concern on this. This is a 4T45E trans and that code P0973 is a 1-2 shift solenoid circuit code. Have put lots of solenoids in these for that, also wire damage on top of the trans for different circuit codes, especially rodent damage.
@@johnhnetkovsky8917 oh snap... I only listened to the video. I didn't realize the codes were displayed. 😬😅
@@CubasAutomotive No biggie.
@Cuba's Automotive I plan on it next year. It's just difficult finding someone to take care of my kids while I'm gone, so I gotta figure that part out.
@@ADVANCEDLEVELAUTO very understandable. Family 1st, especially the little ones. Well, I hope los abuelos or maybe they have a titi to help you out. Lol 😬😉
Nice video and nice to see you doing everything, besides electronics jobs :)
As usual gas level on E. Great video. Can't wait for part 2👍 👍 👍
Hope this customer has deep pockets. They're gonna need them with this car.
Excellent diag bro!
I'm working on a 2010 Malibu 2.4. Had a #2 misfire so I replaced #2 coil. Now it's got a p0300.
Awesome stuff as usual brother 👍 so much good info in here
Thank you for fixing my car
So do sparkplugs not go bad? Or was that one still in okay condition? Dope vid, gotta show off the prndl hair ball in part 2
Great job, You would make a great teacher. I look forward to more videos.
Did you check the compression in the other cylinders? The second one checked at less than 100 psig which is too low. A valve job may not fix the engine?
Waiting for part 2
Good luck 🤞 I learned a lot from you
Oooch! I heard it on the first take after you swapped the coil and experienced the hard start. Was thinking this has to be something more than ignition. Painful news!
Ouch. I hate that situation. Thinking the best and its the worst. I been there a few times.
I'm just glad when I discover the cause.
Nice and complete diagnostic!
first thing i always check on the later model vehicles is a load test on the battery. a weak battery will cause multiple problems throughout the computer
It wouldn't be a bad idea to do a leakdown test on the fuel injectors. Sometimes a partially plugged one can overheat the exhaust valve and burn a chunk out of it. I realize this one appears to be bent or the seat in the head is fubared, but just saying.
The part 2 should be interesting: finding out why the valve travel seems shorter (not seating) or appears bent.
How do you do a leak down test on a fuel injector
Great video, this one is going to be costly. . . ...
Excelent diagnostic.👍
My car seems to have ALL the symptoms this car has. My coils and spark plugs are good. All I can do is pray and hope it doesn’t need a new head. I don’t have the money to fix it. It’s a 2010 chevy cobalt Lt 🙏🏼
How did you initially know that you weren't on the exhaust stroke?
Thank you Eric.
Hey Eric, great diag. Have you seen or used the Autel MaxiAP AP200 OBD2 Scanner. It uses your cellphone and a dongle to connect. Let me know if you've ever tried it and what do you think about it's functions and capabilities.
That vehicle is Beyond Economical Repair. Money Pit on Wheels.
Misfire day for you and me LOL
Hopefully your misfires don't require replacing exhaust valves 😂
Hi Super Mario and Hi Eric, I hope you guys are doing well. 👍 Thanks for another diagnostic video. Eric, I really appreciate your content and hard work please keep it up buddy.
@@ADVANCEDLEVELAUTO haha, no, got lucky
Nicely done ✅
Cylinder no.2 is misfiring on y cavalier.. new coil pack , icm ,plugs and fuel injectors.. still missing 😕
Hi Eric, please, where is your shop?
Part 2 ...YAY
Thanks
Thank you for your generosity!
wonder if they make for other brands
Hey bro, is the scanner the one to get or a tech2 for a 2005 Tahoe? Thanks for your input.
I had a bad coil pack that caused mine. Another time piston 2 and 5 exited the block and it ran on the other 4 pistons and sounded like a Subaru. And the blend door actuator that clicks is sooo annoying.
Where in houston are you?? Near Humble/Spring
Wish I 4 hands so i could give it 4 thumbs up!!
great video
Do you regap plugs when you clean them?
I like your videos. Very Good 👍 some day I would like to be like you( smart)
Hey, thanks

Grasias

This seems familiar to me .... almost like I just fixed this same problem on a hyundai.
The great master
Variable valve timing. Glad my Saturn ion is an 06 instead of 07
Where is the VVT silonoid located
Eric, the link to your Amazon account isn't working.
❤️
hows it go/
What bi directional function does it have for an 04 buick lesabre
You should be able to see that info on the tool manufacturer's site. Or better still email them.
Where is part2 i can't find it
Had a cobal did not want to shift was a wire on back was burnt
Please tell me again what that code reader is
Launch x431 Elite GM. It's in the video description with a link to purchase.

Where is pt2?
How do you check for an electrical problem if the check engine light isn't on? None of the mechanics will put that computer on it because there isn't a check light.
1:20 mark?!?! Who's in the trunk?
