So I'm sure this is somewhere in the forum but digging through so many threads is making my eyes bleed!! Heres my problem, my cobalt is throwing a p0352 code along with a p0300. Now I suppose the first code is throwing everything else off and thats why its running like ****. Now the p0352 indicates theres a bad circuit for ignition coil #2 and I've taken a volt meter to see whats going on. Seems like i have a bad coil. The thing is that i switched to a different position and its no longer giving me the code. The car jerks at very low rpm while trying to accelerate, once the rpms have past about 2k its seems to be fine for a bit. Other times is jerks when the gear is a little too heavy and you try to accelerate. Please help!!!

 

Try replacing said bad pack?

 

Yes, however, when I bought it of eBay it was listed as new oe but I received a used one. I'm trying to figure out if this is bad as well. Trying to find the specs on what the ohms should be to test cool and hot after running a bit. Might this make a difference? Maybe intermittent failure or do these go bad and that's it?

 

Is the car tuned. And have u changed ur plugs. If so wat gap did u set them to.

Check out the problem section on here might find something

 

I set the gap at 33 I believe. I'm using the one step colder plugs that ZZP recommends. Other than my clutch and intake,the car is bone stock. No tune or anything.

 

try a different pcm as there are 4 coil drivers in it

and post my car is broke help me fix it in the problems and service section not the performance section

 

So here is the update. I tested the coils cool and then hot. I came to find that one of the coils is bad. New coil is on its way. There isn't suppose to be any resistance between certain points and my coil is showing resistance between those points when hot.
