Took my 06 c2s into the shop to diagnose the check engine light. My mechanic scanned all system and it stated that it may have misfires intermittent in cylinder 6. He stated the car was running fine and reset the light but to keep an eye on it. Drove it home and no issues. This evening started her up and back pops the light.
Is there a way to reset? Car seems to run fine any advice would be appreciated. Has about 42k miles on it. Also a bit worried if I keep driving it with the light on.

Any smoke out the back on hard acceleration? Any issues with oil consumption?

take it back and re-scan.....if it is still #6 misfire change the coil and lab scope the CPS to be sure

You need a Durametric or the like to reset it yourself.
It happened to me on the odd occasion when I started it up just to pull it out of the garage without running it for a few minutes.
Now that I'm aware, no more quick on/offs with the ignition and doesn't happen anymore.

No issues with black smoke or oil consumption. It happen once it "warmed up" and the rpm went below 1000. Drives fine, taking it to my mechanic.

Yep Durametric tool a must have tool.............o2 sensor I had one that was giving check engine lights intermittently ....? easy DIY to replace

So would the the CEL ever disappear without resetting? If it Doesn't misfire?

Which code was visible? When I get occasional P030x codes (with NO other symptoms), I just clear them with my Torque app and OBDII sender.

Any cheap code reader can clear it. I used one from autozone and it worked fine.

took it to my mechanic and he said the coils are all split and need to replace.
he is not sure what caused it, however not a common issue, anyone else with these issues?

myw

very common. make sure to get the newer design coil packs with the larger base. they are better quality and shouldn't split as easy

guppychao

So how long do they last before i have to get another set?

gpjli2

Not sure I get where this is going

Just wondering if it's due to how you drive the car. I don't track it (would like to) but do drive it hard. Just wondering since myw stated it is a common issue, how often do u get it replaced. I have a cayenne where I have already replaced the coils 3 -4 times. It seems since the coils are relatively cheap that this is a known issue. Wondering what I can do about it to preserve it longer. Or just suck it up and not worry.

myw

suck it up and don't worry.... the newer coil pack design is literally 30% larger imo, i believe they are made better to prevent it from cracking so easily as its a known issue. my first set of coilpacks were all badly cracked by 20km, literally 13k miles.
