I did something similar, with the car in ignition mode I pressed the gas pedal fully 5 times and then shut the engine off. I had misaligned the TPS fitting the first time, I had it dialed in, but not flush with the throttle body. Second fitting solved that problem. Car still has power problems though. P0300 was the latest error. Sparks and coils were just redone, fuel line pressure to before the injectors seemed to be fine.... so I guess it is the oxygen sensors, or CC..... I guess I will find out tomorrow at the shop.
