No I didn't find the problem I can't get the one reader to work to tell me a problem if there is a code. It says communication error won't link up. Then after changing the radio from factory to aftermarket the reduce engine power and service engine light won't go off . Truck won t run over 39 mph and headlights won t work.
Yes you did,Your issues started after you put in that radio,that's your issue,Pull that radio out and reinstall the factory one properly and your issue should be gone.
