Engine Performance problem
1987 Ford Mustang V8 Two Wheel Drive Manual
hey im doing a restoration project on a fox body 87 gt, I have done some modes such as cobra intake upper and lower, bigger throttle body and other bolt ons, I also have done a maf conversion. The car will run but idles up real high sometimes and other times it runs fine. I changed the idle air control and am now looking at the tps but cant tell if this is actaully causing this, when I adjust the tps it gets better but still idles rough and seems like there is a vaccuum leak, I cant find one tho, do u have any suggestions, this is a stock tps but dont wanna replace it until I kno its junk. Alos I have rmoved egr as well, could it be a dirty connection to the map box maybe, any input will help. Thanks
have the same problem?
