my 93 has some issues. The truck is doggy on the road plus it has a crappy idle.
The way it runs best is when the EGR vacuum is blocked off and the TPS plug is pulled. Any ideas?




P.S. I have replaced the plugs and wires, and swapped the coils if that means anything

 

UPDATE: I scanned the ECM for codes and I pulled 6 codes. I don't remember most of the numbers but I do have the definitions, MAF signal too low AND too high, TPS signal too low and too high, EGR not closing and the kicker, code 218: loss of IDM signal on left side= bad coil.
