I'm very glad I could help. The new it was a really common issue with these cars going all the way up to 2010 so I figured I'd post a small video about it
So my cobalt has an ignition pack or whatever it's called. All 4 are connected by a big plastic piece that bolts to the valve cover. Did you do an individual coil pack conversion or did some cobalts come out stock like that?
I just got my G5 a few months ago & I don't know 2 much about it but, I know my last fors had a iac valve ( idle air control valve) & it ran like crazy when it was dirty, stalling!!! Idk if the g5 has a iac valve? The easiest thing I can see with your 2.2 is to clean your throttle body !!!! Unplug it 1st!!!!!! B4 cleaning it, definitely unplug it!!!!!!! Mine is slipping in overdrive when I let off the gas/ coast... only in 4th gear! Hoping its the filter!!!!!
I just finished working on a 2010 Cobalt and his variable valve timing was out. It was stalling and sputtering all over the place until we replaced that sensor
I 100% agree. We're also supposed to put electrical grease in the boots every time we change our spark plugs and put grease on the backside of brake pads so they don't stick to the piston. There's a lot of little details we're supposed to do every time that we never do
Im not a pro either but I believe it would just make it misfire and idle poorly for a moment plug it back in and it should go back to normal. Its not "good" for the motor but it wont do anything crazy. When I have questions like this I always research until Im comfortable and then apply what I learned
I am sorry I just now noticed this. But unplugging and running the coil unplugged for a significant amount of time will cause damage because there's no combustion in that cylinder. But if you do it just to test which cylinder is already down for a brief moment you're not going to cause any damage.
I bought my 2009 Chevy cobalt and the mechanic said cylinder 1 misfire and that the best thing to do is replace the motor it's to much money ,he said the pressure was 90 psi
Taking on a #3 misfire in my 07 G5 today. Thanks for the vid!
@@TJN816 glad it could help
bro you just helped me figure out how to find the misfire!! thank you

@@CmfBaker yeah thanks again man i just couldnt for the life of me figure out witch one it was but i got it now you are awsome.

@@Barncat01 I'm assuming yours is a 2005-06. They switched to individual packs in 2007.
You're a good teacher!
Thank you it is perfect lets see how she runs after.
@@felinasunshine8537 hell yeah! Glad to hear
My cobalt glove compartment will not stay open it springs back shut. Any way to fix that would be helpful! Thanks.

At idle pull the fuel pump fuse to kill the engine and relieve pressure or there’s a Schrader valve on the rail itself
@@cooliecrewspeedshop you saw that huh lol.
I got a 2008 cobalt sport just got it yesterday. I’m thinking mines have the same problem
Thanks ! Helped me immensely
So should I replace the fuel injector
I learned something. Thanks!
I am not a pro , But I no a lot about everything !!!! You go......
you helped me out boss thx!!
thank you
Should always lube o-rings!

Definitely nice when the ignition coils are separate, not like this 2006.. lol
Agreed, plus the ignition control module right on top of the coil packs for a 2006 it just cooks that component to death
I read that unplugging the coil while running could cause damage, does that not apply to Chevy cobalts?

Good shit thanks bro

Yeah replace the fuel injector and possibly the fuel pressure regulator
What was the trouble code?
It was a very basic Misfire code.
