hey scotty, following with the mustang i posted about a week ago, 87 with 2.3 and j checked for vaccum leaks and didnt find any and cleaned the throttle body amd still
idles pretty high at around 1,200 rpm and doesnt go down. Also ive noticed it throwing out a high amount of white smoke even after idling for 5 minutes what could it be? thanks

often a blowing head gasket, do this test https://www.youtube.com/watch?v=QA7KVQq9vKA
