I have a stock Colorado, that has been going into reduced power mode only around 40-60 mph. I had the throttle body replaced and the mass air flow, it is still doing it after those two. I don’t know too much about the truck so I’ve been watching some videos about how it might be my 02 sensors but when I went into autozone and they did their own scan they found that it wasn’t those. P00171 and P00068 are the only codes it’s throwing right now, 2 171’s to be exact. It idles really rough and bogs heavily before going into reduced power mode, which has me thinking it might be an exhaust manifold leak. I’ve watched hundreds of videos, I hooked up the vacuum and did the spray bottle but couldn’t find anything. Granted I don’t have a lift so I was crawling on the ground and might have missed a crack or something but to be honest I really don’t know. I’ve been having this problem for awhile now since it shuts off 4-5 times a week. I’m tired of dealing with it so if anyone has any cost effective ways or really anything to get it to just run normally that would be super cool. Thanks

don't use aftermarket parts for any sensors. Most are crap and you have no way to check them.
