Hi,

When i drive with the TPS unplugged, the car drives great, but when i plug it in, the timing seems off, car is underpowered, small backfires as it revs down. I dont want to play with the timing, will the ECU eventually compensate and adjust timing with the TPS pluged in?
Things to note: I have just replaced the TPS because the old one was broken, and i adjusted it to 0.450v at idle.

If i do have to play with the timing, is there anything wrong with the method of adjusting timing by setting to TDC, removing valve cover and re aligning CAMS? , or even easier, rotate CAMS until she feels normal again?
