After getting my defective coil pack replaced, I thought I’d give you a list of symptoms to identify this problem. I looked in the forums quite a bit and was able to piece the information together but I thought I’d share a detailled list of symptoms so others can identify the problem more quickly. Maybe this has been done before, but just in case here it comes:

• The car starts running very rough, especially at low revolution (between 1-4K RPM) and you can feel it shake in the stick and pedals. Seems less apparent >4K RPM.
• I noticed a different sound (louder than usual)
• Smoke from the exhaust not coming out as a steady stream but in chunks (“puff puff puff”) instead of the usual steady (“rrrrrrrrrr”)
• Very noticeable lack of power
• Sometimes, the RPM drops while accelerating (RPM would drop from 3.5K to 2K for no reason at open throttle)
• Sometimes, the SES light comes on and/or blinks while accelerating
• The SES code was [P0302] CYL 2 MISFIRE

I know there are other problems that can cause these symptoms but if you’re experiencing something similar, you should get your coil packs checked (or check them yourself).

Please feel free to add to this with any relevant information!!
