I has a 97 Mustang which I have placed a 5.0. It has been one problem right after another. Finally got it where it will run,but now it won't idle and it stays revved up when changing gears. I've replaced the IAC. When the engine is cold,it runs like a dreams. After it gets hot,it seems like all the gremlins want to come out an play. The other day I was a cross town when the car started acting up.Would not idle down,stopped on the side of the road and unplugged the IAC. It ran great but a lil sluggish. I'm at my witts end.Can anyone tell what I need to do to get this car to run right!!!!!!
