One night I was driving home and I pulled out and gassed on it and the service engine soon light came on. Well I took it in and they changed the coil and that was it. They said it was from reving up the motor w/the flowmaster exhaust. Is there anything I can buy to make the coil NOT mess up like that again?

 

I dont know why you would want your coil to mess up again, but no revving it with a flowmast exhaust will not cause any problems with your coils. They are yankin your chain.

 

i meant for the coil not to mess up again..sorry bout that

 

I wouldn't not go back to that mechanic for anything...

 

You said the SES light came on, did they tell you what that said?
