I have a 2000 Mustang GT, my car as recently been idle at 1500 rpm. I have replaced the IAC valve and checked the throttle position sensor, from what i can tell all my hoses are connected as they should be. My car is pretty much stock, w/ cai and exhaust and i have not changed anything recently to cause a problem. Does anyone have any idea what could be causing my high idle? I feel like it a sensor or something computer related but im not too familiar with the sensors and cpu on the car. I would appreciate the help.

Clean your maf

get some t/b cleaner and spray it in your throttle body,see if that helps, my problem was my car was revvin up to 5k. trust me annoying as hell.. i finally just adjusted that screw that was in between the throttle cable to the t/b itself.. finally just took the scew out.
