Rewired TPS, new and worse problem now.
Initial problem: Car would occasionally sputter while driving. Fiddling with TPS plug or wires coming from plug would relieve problem, if it didn't go away on its own in a few hundred feet.
Put 100 miles on car this morning, mostly driving well. 1 trip to 7k in 3rd, pulled like an NA should. Was running fine when parked to do this: I re-wired my TPS. To be specific, I ran all new 22ga wiring from the TPS all the way to the ECU where I cut and butted the two signal wires from the ECU into the new wires, and I cut the ground on the ECU side of the existing split to make sure all wires stayed grounded in case there was a split in another part of the harness I didn't know about. I aslo added an additional ground to this point. When I started the vehicle, it sounded a little rough but ran up to 3k and when idle fell it died. It was flooded. I re-set my TPS with the ohm-meter-test-connector method to no improvement (although, it was off). I can get it around the block with effort, and i can rev to 7k in neutral with light even throttle input. If I gas it hard at all it is like all spark goes out immediately and when I let off the throttle it bangs out the exhaust (first fireballs were supposed to be at speed, not parked ![]() Hard throttle and it falls on its face at any RPM.
