*HELP*Misfire Codes Continue to Occur - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

This is a question to anyone who can help me shed some light on this. I have a 2012 2ls Camaro. I' at roughly 44k miles and have a GM PP warranty still on the car.Cylinder 3 is misfiring, i've swapped coil packs from cylinder 3 - 6 and it still occurs. I've taken it to the dealership for years now and finally two months back they stated that carbon build up was the reason for my misfire codes in the cylinder. They replaced a coil pack and cleaned the carbon out per the GM techs orders. Back not even a year after I purchased the vehicle in 2013 cylinder 3 had misfire codes. The tech and the GM dealer replaced the coil pack on the cylinder in question and everything was fine for a time. Then the code came back randomly for a few years and if it did happen I could never get it to occur for the dealership. So I finally was fed up with it. Now its happening again after all of this and they charged me 335$ for the carbon cleaning stating that it was wear and tear. Which is understandable. Can anyone offer some advice? I'm in my last year of college and cant afford to keep dropping 300$ every two months to have them clean carbon deposits.

Has #3 cylinder plug been changed?

BubbaSS · 06-28-2016, 01:44 PM

Do you know the exact code? Does the car feel like its misfiring?

tuki3388 · 06-28-2016, 02:26 PM

it was a P0300 code, the notes from the dealership from my last visit state, replaced injector 3, removed intake, cleaned valves 3 times, could not duplicate after that point. But now the code is back roughly 2 months later.

As far as feeling this misfire, back when the code was popping up daily I could. Now I really could not. It generally occurs between 40-60 mph and in 3-4 gear. I've been doing lots of in town driving due to being in college but when I go home I run 70mph interstate highway the whole way. This is when any issue normally happens. So for the last 3 years I go home two times a year so.

As far as I know yes, and I have swapped it cylinders. The whole coil pack or what looks like a railway spike, (sorry not too mechanically knowledgeable) has been replaced. I believe it was 130$ or so.

To be clear, the spark plug has been changed.

maddoggyusa · 06-28-2016, 04:18 PM

when you get a misfire, can you feel the engine acting abnormal??

if no, I would probably just not worry about it unless it's under warranty and then I'd make them fix it.

if yes, then it's a warranty issue. you don't need to keep cleaning the top end every 2 months. that's not normal.

tuki3388 · 06-28-2016, 04:28 PM

before I got it cleaned yes I could feel it, but after it no. I'm coming up on the last year for my GM PP warranty and my power warranty. I just want it fixed encase of future issues. Its been doing this the life of the car technically. I'm just worried due to financial reasons, last year of college, last year to pay on car, and I don't have a lot of money to be throwing around yet.
