Engine Performance problem
1992 Ford E-Series Van V8 Two Wheel Drive Automatic 78,000 miles
Runs like it is choking all the time. Black smoke when starting and when on the road step down on the gas more black smoke. I have changed many parts. O2 sen, temp sen, manifold temp sen, egr position sen, egr, map sen, all vac lines, cap, rotor, pluges, wires, fuel filter. I have checked the grounds I could find.
What is good fuel pressure? Where is the regulator?
How do you check injectors? Is there a voltage?
My o2 sen is running at.9 volt.
have the same problem?
