Question about 1989 Ford Mustang
The car will be hard to start have to give it gas but when it does start it revs to about 4k rpms and then dies. The longest it has lasted is about 15 seconds
Sounds like the idle control valve. The same thing happened to my Mustang and that was my problem.

probably is a emissions sensor problem, lots of these parts are plastic. check out the throttle cables, lub em wd40. there is a type of valve somewhere on top of engine, it may be cracked, pcv valve stuck. lots of possibilities, almost too much for solution online. something emmissions with an electronic sensor is acting up.

check all spark plugs and wires also check mass air flow senser located on intake tube if all is still in good working condition check the throttle position sensor if that is good then it may be your fuel pump please update when possable.

It could be your idle air bypass valve. They get sticky with age and don't let enough air around the throttle body to keep the car running when it's at idle.

Testimonial: "Hi Nick, I took it apart and soaked it with intake cleaner spray and it worked! I also replaced the gaskets in the throttle body. Thank you. :-)"
