My friend installed an 86 5.0 Mustang engine in an older Ford Maverick (74 I believe). He used a Painless wiring harness. The computer and throttle body are from a 90 Mustang. It has a custom air intake with MAP sensor installed.
It will start, but the idle varies, stumbles a bit and runs very rich. Seems as if it's dumping fuel for some reason. He's been struggling with this last bit of the install for a month now. Any insight would be greatly appreciated!! Thanks you! Joe
