Car on no dtc's. Haha don't think so, key to on but engine off 2 codes showed up on the scan P0350(Ignition Coil, Primary/Secondary Circuit. What's this all my coils or maybe my ICM? And the other code which I do not know is P1350?
 


P1350 should be for Ignition control (ICM), IIRC. Might want to have the ICM tested and see if it's good. Also check the wiring going to it.

thanks, I did a little research but I think its my icm. The coils are only 102000 miles old and ive been told the icm is more sensitive to water/coolant!
 


The difference in icm's is the brand. The dealer's is likely Ac delco although some of the electronics might be Delphi, autozones is probably duralast. You can also look on rockauto.com they sell Ac Delco and Delphi as well as some others and are significantly cheaper than the dealer. I also like to get the part number on rockauto and then look up the number on amazon.com because sometimes they are cheaper too.

I think autozone can test you icm to see if it's it bad. And also check the for sale section anyone parting out a car might have a used one for you.
 
They will all fit the same but how long they might last is different story. The autozone one is worth it if it has a lifetime warranty, but if it doesn't I'd go with one on rockauto, Ac delco, Delphi, or Standard would be my choices
 
I never buy electronic parts from Autozone, lifetime or not. I don't like changing parts out every 6 months even if it's got a lifetime. I don't have patience for crappy parts, lol... RockAuto FTW. If not, maybe check the above that Swiggles mentioned, or OReilly's. FWIW, when a cracked coil took out the ICM on my 00 GT I replaced it w/ a OEM used one that I had from my old motor and it still runs fine. Had 200K on it when I swapped it in and am at 279K now w/ no issues. Just sayin..
 


Ya I definitely agree with you there. advance auto sells Delphi as well but they are cheaper at rock auto usually, sometimes shipping costs more than what you are saving.

So I swapped coils and they were good then looked at the pins on the ICM they were fine also got a new ICM problem solved no codes, everything seems/feels better.
 


i had the same issue but mine was cuz the bolt from the wires where it plugs into the icm wasnt still loose so once i tightened that up my car hasnt studdered since.
