1989 Mustang 2.3L Ford Factory Swap out to 5.0L Idles rough, dies hot... HELP!!
So, I just bought this car that had a 2.3L motor swapped out before, and a 5.0L put in. Not a hack job, done by Ford, and confirmed it was proper by Ford, I have some sticker on the rad. Anyways....
The car will start, crank over twice, and fire until its hot. Once it gets warm she dies, and takes for ever to start unless you let it cool off. The alternator isnt in top condition, but even with a battery charger hooked up it will still die, so it cant be the injectors losing power and getting it again. It is almost like it runs out of fuel, and than sparks and shoots up the rpms again, but with the fuel pressure gauge on her she runs 35-45psi strong.
Im puzzled... any helpers?
I Have tried:
a new MAF (Mass Air Flow Sensor)
a newTPS (Throttle Positioning Sensor)
a newComplete Distributor and Moduel
Switching out coils same thing
changing Intake manifold and plenum gasket
