Hi,
Started noticing I am having abit of a rough idle. Especially when cold i dont notice it as much in gear but in neutral idling. Even when its warm it has a bit of a rough idle. If i bring the rpm up to 2000rpm or higher when its warm it revs fine, but i notice when its cold and i bring the rpms up it still has a bit of a rough idle. I didnt see any air intake leaks, the car has about 55K miles on it and is a 2003.
Any suggestions on where to start? Plugs seemed OK so i didnt change them. I only checked one per bank though.
