2013 GMC terrain Denali 2WD 2.4 L - the car has 167,000 miles, it has a new transmission rebuilt 1 year ago and they just replaced the torque converter.
I have replaced many oxygen sensors, both VVT solinoids, Coils, spark plugs, Map sensor was replaced by a shop.
We have fixed your car and I get in and in the parking lot or a block down the street it stalls out again and dies.
I can only drive it at higher speeds and runs fine but when starting out or coming to a stop it can start to run like its missing or loosing rpms, or running out of gas. I have even had a shop bring in a master scanning tech who fixes everything only finding a MAP sensor problem they replaced 3 times. He said now I must take it to a dealer to fix. It can not be fixed by anyone even the dealer for loosing rpm sputtering or choking out but always starts
I had to by a newer car and just want to sell this but I can't because it is not reliable. Everything else looks good. I use redline injector cleaner, Bardol sealer smoke additive. No oil leaks , all system check out good fuel presser, all good.
Please help when you can.Thanks, Arch long time fan of yours.
Well, of course I'd have to see that in person to do a true diagnosis, but those things are notorious for having fuel injection problems and at full speed if they're going full blast and it runs, but it won't do it when you're going at lowers speeds that's often a sign of fuel injector failing. I would have them tested first
