Hopefully somebody can help me with my dilemma. I recently replaced the stock 302 with a 302 ** from enginefactory.com and am unable to get it to idle.
Here are some of the symptoms I am experiencing:
1) starts cold w/o pressing on the gas and dies about 1 minute later.
2) black smoke coming from exhaust with smell of gas
3) will not idle besides initial startup when cold
Here are things I have replaced or cleaned:
1) cleaned Idle air controller
2) cleaned throttle body
3) New Sensors: tps, oxygen, map, ect, act, egr
4) New fuel regulator and fuel filter
5) new battery cables
Things I've checked for:
1) vacuum leaks (none found)
2) codes (none)
3) fuel pressure (38 psi)
4) spark (present but looks weak)
5) timing is good
6) no fuel leaks around injectors
The engine runs smooth over 1000 RPMs. The only thing left I haven't tried is switching the stock injectors (19 lbs/hr) with the 24 lbs/hr that came with it. It is running way too rich and maybe this would help since I am still using the speed density computer.
The other thing I was wondering if I needed to swap the wiring harness and computer from a 5.8.
Please Help Me!
