And just as a FYI the guy that had the car before me had the Injectors cleaned before i got the car from him. They were cleaned about 7 months ago and i got the car 4-5 months ago

Cleaned

i had a picture of the 'seat' but i can't find it... i thought it was on photobucket but i guess not.

By the way, where do you go to get the gaskets other than the stealership?

Ok Guys here is an update. I turned on the car, let it warm up and went to the ECU and turned the dial all the way to the left. Went to the IAVC and adjusted the screw on it until i reached a constant 800 rpm. i turned on the AC and the rpm drop dramatically. So i started adjusting again until 700 to 600 rpm and the car stopped shaking. then went back to the ECU and turned the dial all the way to the right. The car is OK but not perfect. It hasn't stalled anymore and doesn't tremble as much. But i am thinking this is only the iceberg of the problem. Why would this happen all of a sudden. This is the first time i ever messed with the ECU so it has not been touched before. What could cause this problem to happen all of a sudden?
