For those of you that have read and replied to my other threads thanks and with your help I thouhgt I had whipped this thing. I got the stroker in did some driving trying to get to the 500mile mark all was good. Did the normal headbolt check, valves, and oil change. When I drove to Mississippi yesterday about 115 miles into the run the checkengine light came on so I slammed the brakes and pulled over. All seemed fine by ear nothing crazy. When I checked for codes I had 41 (TPS) and 52 (Knock Sensor) I cleared the codes by pulling the battery cable and got a ride. When I drove the truck home nothing happened no light, no codes, nothing. Was this just a glitch or what? Oh and yes I checked the TPS all is good and it's my birthday so help me fix this.

 

I think that unless you have an electric connection problem, it was probably jsut a glitch. Your best bet is to run through the FSM diagnostics that pertain to the code numbers and see if anything doesnt check out. It could have been a glitch, and without it throwing codes again, you havent got a problem. I would be worrying about them if I were in your shoes too, though.
