last saturday i was at a stop light and lost acceleration completely. turned the car off and restarted it a few seconds later and had acceleration for about 5 seconds then gone again. no noises and engine runs fine, tranny engages and i drive home at about 1-2 mph.... long trip! bought an obd ii code reader from sears and got code 2112, 2238 and 2241. i need a list of the codes and directions on what to do to rectify them. Could this have happened because I had changed the plugs and when i put everything back together i did not plug in the throttle position sensor until after i started the car and realized i had no throttle control??? i erased the codes today and it works fine now and the codes did not come back after i drove the car.... in my complex... for a few minutes... any advice please?
