Got a 02 Chevy lb7 with edge programmer and always throwing codes, tcm and fuel temp sensor, always delete them and never worry about it, well couple months ago when it was still cold I noticed my truck wouldn't go over 10K on the desfrp, and frp, both at 10.1, thought was gelling so replaced both filters and still nothing, cleared codes and noticed another code about fuel pressure, but can't remember what dtc number was, anyway took my maf, and map sensors out and cleaned them with maf cleaner and been running fine since. Today noticed codes were back, two tcm related and another fuel since temp, driving 4 hrs on vacation in a week and don't want another problem, think these codes are just flukes or is that fuel temp sensor gonna send my truck in limp mode again, I mean haven't checked codes in a while don't know how long it's been in computer and trucks been driving great. Any one else had this issue?
