I replaced all the spark plugs and coils and the car ran like a champ for about 2 weeks. I got in the car the other day after washing it to drive around the block to dry a little the water off and the car hesitated to accelerate. The CEL light was flashing. I pulled codes P0300, P2187, and I think the other was P2177. I'm aware of the gas cap being broke in two pieces, that being said I'm sure that where the other codes are coming from. Is it possible the coils could just be bad? I can drive the car about a mile or two and then it'll stop hesitating and drive fine til the next time it sits for a lengthy amount of time. Any suggestions? I kept my 4 old coils so I thought about putting them back in the vehicle and seeing what happens. I think coffee P0304 is pending. Could it be cylinder 4 misfiring and causing this issue?
