I recently bought a 95 mustang from a freind of my moms and it has an idle problem and was wondering if someone could help me.When you start the car the rpms go up and down 200-300 and tries to die when you put it in gear and also dies when you come to a stop. It was originaly a 6cyl car but was was converted to a fuel injected 5.0.It has had many modifications done to it such as a intake from a cobra mustang,cold air intake,headers,roller rockers,aluminum heads,bigger injectors,bored out and many other things.The guys says it makes around 450-500 hp.I don't know what i exactly in the motor like injector size,the bore,valve lift.I was told i needed a stall converter but Im just 18 and dont know.Any help would be appreciated

had the same problem there is a plate that goes in between the IAC and the intake it has an adjustable screw in it to adjust how much air enters the engine at idle ,,mustang unlimited sells this piece part#f2933 01 check into it ,it may help] if you have a stock stall converter then a aftermarket converter around 3000 to3500 would most def help
