1992 Explorer 4.0L w/Auto OD
A fairly significant vibration while accelerating (side mirrors vibrate badly).
Vibration quits once you let off gas.
U-joints and drive shaft bolts look okay. Trans fluid okay.
No slippage from a standstill. Shifts to all gears.
Tires and wheels okay.
Engine smooth w/no miss while in park or neutral.
Tach bounces around about 500 RPM when vibrating.
Seems like power-loss and/or miss (spark advance)
No vacuum leaks. New plugs/wires. All connectors/wire seem okay.
Code scanner said throttle position sensor but replacement didn't help. Still get code.
Any ideas?
thx in advance
