Hey everyone, I recently put in a jb3. After install everything was fine. The next day I put it from map 3 to 0 and then back to 3. I whomped the car And it wouldn't shift at the high rpm and the car went limp and started to shake and run rough. I turned it off put it in map 0 and took it to auto zone. The service engine soon light came on and was pulling code P0335 crankshaft sensorA malfunction. That code went away Nd now I have P142E code running the service engine soon light. I took the tune out and got the codes cleared Ans I took the car out for a drive, put it in sports mode and whomped it and it went limp again, wouldnt shift at high rpm and started running rough again and shaky. Any reason why this has happened?!
