My freind mike has a 88 5.0L mustang and is not sure why his car idles like shit. We adjusted the tps, I think that what it was I dont know alot about this car. But He did spray cleaner in the throttle body and the car ran smooth and nice so were not sure if its the throttle body that has a leak in it or what. Like were the plate goes? any other things to check? We checked the ecu and its a code 22 (MAP) sensor was bad but he replaced it with a new one. The tps thing we adjusted tested fine WOT is suppose to be 4.84 and closed I dont even remember? Does anyone know what or any help on this please?
