Hello everyone, I'm relatively a noob to subies, I have a 00 RS, excuse me for any "dumb" questions. Ok, I've had a check engine light for 2 years now, thought it was the Borla headers, but it hasn't caused a problem. Recently I started having hesitation, kinka like a fuel shortage all of a sudden while accelerating. Then now it's worst, sounds like it's missfireing and while accelerating it jerks. Srry for the long post and grammer, Pleeease help, it would be greatly appreciated.
