Iv recently run into a problem with my Throttle position sensor or somthing along those lines. While im cruzing on the interestate the throttle position % on the SAFC just goes nuts and makes the car kinda jumpy cause its adding and taking away fuel really fast. The throttle % was bouncing from 0.0% all the way up to 100% even at idle.
so i dont know if its bad wiring with the safc, or if its the actualy TPS.. any ideas? and the problem comes and goes. Seems like it starts doing it if i boost some.

well the throttle problem was the TPS, it needed adjusted. The check engine light is still on. I borrowed a friends afm electronics and put them on my car to see if it made a difference. His electronics actualy made my car run worse than what i already had on it. so im not sure whats going on there. His electronics are in good working order to. as for code 14 what should i do??

swap ignitors, double check to see if the cps is within spec per tsrm.
Reset ecu, start it and check to see what codes reappear

As I said in the PM I just sent you I bet this is all caused by you AFC wiring, it being taped up and then pulling the hardness through the firewall hole I bet knocked it loose.

Next weekend Matt and I will be at his parents house again starting on my car, if you are still issues stop by and we will take a look at this.
