C1248 is TCS disabled, most likely from your dyno run.
the P0200 is probably from you injector swap, as this is showing an injector control fault. YOu may have an injector that is not showing the correct resistance, therefore, the monitoring system that check the control circuit is seeing something it should not see.
What kind of injectors did you put in????
If you absolutely need to, you can stop by, and I can do a quick scan, and let you know what is up.
Just let me know first, ok???
I will recheck in the morning, besttoyou, c4c5:z:
I did not reset the code after thr dyno. I have now. The P code was a loose injector plug which I have fixed also. I will see you the 27th my trunk will not open with the button. I did not do the injector swap fro warranty reasons if there is a reason? BTW Dan's son is my neighbor, I appreciate the fact you would let me come by a scan the PCM for me in the back lot, but I "know the owner" so I don't think he would ahve a problem with it. He was disappointed he could'nt get the car for me said he would take care of me service wise.
