Ari-one, I appreciate your time in responding to my post. I was getting ready to test my coils on Saturday and when I took off the valve cover I noticed that the ground to the coils was loose and the bolt holding it in place was not tight. I tightened it and the engine fired right up with no problem. Ran it for a few miles and it's actually running better than it has for a while. However, sometimes when idling the rpm's will rev up and down between 1000and 300 rmps. When I rev it up with the pedal it seems to calm down. It was suggested by a friend that I should remove and clean the IAC valve. Any thoughts would be appreciated. Thank you.
