Engine Mechanical problem
1986 Other Ford Models 6 cyl Four Wheel Drive Manual 100, 00 miles
I have a 1986 Ford Bronco II. 2.9L. It stalls at high rpm. Changed fuel fliter, checked fuel pumps, 40 psi on fuel rail KOEO, drops to 32psi KOER. Changed fuel pressure regulatore, and EGR valve and EGR valve position sensor, and Exhaust gas Oxygen sensor. Fuel pumps are working good. I cleaned all carbon out of the EGR ports and tubes. Timing is at 10 degrees btc. It will start and idels good, but when I apply the throutell it stalls even with no load (in neutral). I checked all vacume hoses, no leaks. The Actron tester gives me a 33 (EGR valve opening not detected), but as stated I changed the EGR valve and position sensor.
I get 16 to20 PSI on the fuel rack whin I try to thriughtel up. I get 5 volts on the ornge lead. On volts on the BLK or Green. But I also get a ground indication on all three leads with the key off.
have the same problem?
