I have a 2000 Mustang GT 4.6 SOHC with 51000 miles....for some reason after i start driving it will be normal until i go to stop, it will idle at like 2000 or sometimes even 3000 RPM's....if i shut the car off it is good....but when i start driving again it will do it again....i heard it might be a few things so i cleaned my Idle air control valve, throttle body, MAF....I have a off-road x-pipe so the MIL light is on....i also have a intake, flowmaster mufflers, throttle body and intake spacer's...but i removed the spacers to see if it would help but it didnt....any information would be a huge help...i dont know what it could be....thank you
