My friend has an old escort (it looks kind of similar to the old fox body i have) and she has to hold the gas and the break because if she lets go of the gas at a stop light and just holds the brake, the idle will dip so low that the car dies sometimes...i'm talking it goes to like 500RPMS (its an automatic) but i was wondering what is wrong? did escorts also have an IAC? cause that was my first thought...thanks for your help!
