I chased a bogging problem on a 1996 2.5 EFI for a week last year. Accidently found the problem while running at the ramp, I was hooking up to check the voltage on the TPS, placed my left hand on the top left side of the ECU and the motor picked up 500 rpm`s. Could not find what was wrong with the harness. Replaced the motor wiring harness and she ran right.
The world will not be destroyed by those who do evil, but by those who watch them without doing anything. Remember what He has done and remember that He is not done yet!-- GOD IS GOOD
