Since the check engine light came on there's a trouble code stored in the computer. Visit your local auto parts store and ask them to scan the computer. Most stores will do it for free. Even though the light went out the code(s) are still in there. Your looking for four a digit number on each code with the letter "P" as the prefix. As an example: P0301. Off the top of my head I'm thinking throttle position sensor or, if equipped, accelerator position sensor. Please post the code(s) and we can help further. On a side note, keep the print out of the scan showing the trouble code(s). This will prove that the truck malfunctioned and that your Son wasn't being careless. HTH. -Jim


Oh mark thankyou so much for your info we just replace all brand new throttle positioning sensor And news pedal from gm and it came back on my son's truck again after 620 bucks later lawyer went to court on sons behalf today but we really looking at 5 gran to beat this picton ont cop even with a dashcam rolling showing no such thing as a stunt driving accusation hmmmmm seems cops can make up lies sad world supposed to be serve ND protect don't think so in this world mark lough thankyou somuch for caring tc all the best to you stay safe regards catherine
