rickyrick562 Posted April 11, 2013 Report Share Posted April 11, 2013 Okay so I was at a light and turned right but as soon as I did that the truck switched to reduced power so i pulled over and shut it down. So I went to restart it and nothing(just lights on the dash) so I tried again and it started and now I have a check engine light but it drives fine. Anyone have any guesses what it could be Quote Link to comment Share on other sites More sharing options...

cmoney23 Posted April 11, 2013 Report Share Posted April 11, 2013 This happened to me im my jaguar. It said "reduced performance" It was a loose connection on the throttle body. Fixed it and never happened again! Quote Link to comment Share on other sites More sharing options...
silverado_ss_04 Posted April 11, 2013 Report Share Posted April 11, 2013 what i have been hearing alot lately is that its always a problem with the tb harness, check for a broken wire. Quote Link to comment Share on other sites More sharing options...
