Engine Performance problem
1992 Chevy Silverado V8 Four Wheel Drive Automatic 148000 miles
Engine was replaced at 71,000 by dealer. Truck is now at 148,000. Slowly been getting worse for 1 year.
Truck starts but then while driving it, oil pressure slowly goes to approx 15 psi. Truck runs rough at all speeds and there is a consistent overall lack of power.
It will sometimes stall pulling up to a stop sign. When the engine start to stall, it stutters and oil pressure and other guages drop to low levels. Pressing on the gas will save the engine from stalling.
I am not sure but I had engine work done by what I am now thinking is a incompetent mechanic. They replaced the distributor shaft, rotor, and cap, etc.
