I have a 89 mustang gt convertible. when i first test drove this car i was told by the owner that the throttle sticks. well that same test run the thottle stuck and the rpm's redlined. i was reading around in some forums that if you have a vavle breather and a mass air meter your computer gets messed up because it cant read how much air is going into the engine. Could it be the throttle cable sticking or could it be from the breather?
