As for the rough idle whens the last time the air filter was changed, are you having voltage drops, or maybe its a dirty throttle body. Good luck!
its just a 2.0 single over head cam. probly the simplist and cheapest enging they make.. filter never has been changed and how do you tell if your having voltage drops? throttle body,maybe.. is that easy to clean/ get to??
