CEL Reduce engine power
I have been having problems with my colorado lately. About a month ago I was just getting off of work, and decided to just rinse my truck off. I rinsed it off, and dried it. I drove off, and 10 mins later, while driving down the road, my CEL came on and my monitor showed a code " traction control/ stab sys service reduce power" and my truck started to shake (i guess when the engine goes in reduce power mode, it shuts of a cylinder or two, cause thats what it felt like.) So i stop at the nearest business, popped the hood, just stare at my engine like I knew what the hell I was looking at, and closed the hood. I sat for about 5 mins and started my truck back up no CEL, and no codes. fast forward to now it does the same thing on and off, its like it has a mind of its own. I went to auto zone to see what codes had been thrown, and two showed. TPS, random engine misfire. Can anyone help me? Its on a 2011 colorado w/t with a 2.9l engine.
To truck or not to truck is the question.
