Engine Performance problem
1991 Ford Ranger 6 cyl Two Wheel Drive Manual 100K+ miles
Strange problem. Started to experience a loss of power. Takes a long time to get the vehicle moving but will eventually get up to speed but any hill becomes a struggle. The engine runs fairly smooth, not like a plug wire is off but there is some slight popping or backfire noise when you let off the accelerator. I have done the obvious, new fuel filter, new plug wires, plugs are ok and maintains fuel pressure of 38 psi at the Schrader valve throughout the RPM range. There is a definite, loud clicking sound from the two aft injectors on the passenger side. I removed the connector at those two injectors and the clicking disappears without a noticable change in engine noise. I thought possibly injectors were plugged so I replaced all six. The new injectors did not improve the problem at all. When I put a meter to the connectors while running I get 12.85 volts. The other odd item is after the engine runs for a few minutes, the plug wires are very hot, too hot to touch. Any ideas?
have the same problem?
