while doing the procedure I accidentally pressed the screw and the car shut off. I also noticed that half the head of the screw had broken itself off. I know this because i didnt apply a lot of pressure. I had done this in the past. It turned back on but now it revs at 500 and the engine light turned on. I disconected the negative terminal to let it erase any codes overnight But not successful. The car still revs at 500 and goes up and down up to 900. This car is mint in every way.
I want to believe that the ecu is still fine.
Will thank all ideas and experience shared. Thanks.
