the distributor was fine until i took it off then it wouldnt want to go back on. now when the car is cold it runs fine then after a while the cel comes on saying code 4. i can shut the car off, let it cool down, and reset the ecu and it will run fine then the cel will come on again. i haven't got the tdc sensor code again yet. and its a msd distributor that ran fine until i took it out. do you think it could be a wire messed up? and the car runs fine until the cel comes on.
