okay i Slowed the idling problem down a bit. I put back the f22 computer back in the car to soften the blow a bit to get me tooo and fro to where i need to go . Will i damage the car doing so? another thing as well the idling problem has lessened a bit . Was gonna go to the dealer today but im not gonna pay someone to tell me what the problem is when i can spend that money into fixin it myself. what that thing called to test to see if you have a vacuum leak? and at what psi should each hose be at starting with numbers on the hoses on the throttlebody. And i need a voltage tester right? where should my tps voltage and my idle air control valve should be at.
