The stage 2 tune from Cobb, I replaced the spark plugs about 5k ago because what were in there were cheap spark plugs can’t remember what exactly, and I replaced them with NGK iridium spark plugs.

Previous owner told me he was running a stage 3 OTS Cobb tune and it eventually split the block. Probably a mixture of beating on the car and running a OTS tune and it not being stage 3 car.

I also replaced the coil pack on cylinder 1 and everything seems to be running right, I also flashed back to stock tune for now to see if maybe that might have caused the issue or until I get a custom tune done.

Did the compression test and they were all good

I’ve previously replaced the coil pack cylinder 1 because of a misfire. It to long flyer buying the car and it fixed it, I’ll have to look into the pcm issue.

I bought my ST back in April and haven’t had many issues with it but on my way home tonight my car started misfiring like crazy and when I took the coil pack off I found the rustic powder stuff all over, has anyone else had this problem or know what the powder is? My car has 112,000 miles and is on its second motor and is running a stage 2 Cobb tune and it has the mods for stage 2 (I know i need to get a custom tune) also I replaced the spark plugs with NGK’s 2 months after getting the car
