06 1500 Hemi. Had the accelerator pedal position sensor go out so I replaced it with a new pedal. It ran fine for a couple weeks then it started acting up again. I ran the code scanner and it showed the throttle body had gone out as well. I replaced that just recently and still have the same problems. The throttle is real sluggish and will take about 1-2 seconds before you get full response. The Trans will short shift like crazy. Need help on this before I blow this thing up.

Thanks
