Truck idles really low, will stall sometimes when I make a slow turn
Idle low like 500 rpm any suggestions on normal idle for this truck?
Engine powered down and stabilitrack off and service traction lights are all on. Can't drive it over 10 mi per hour. A tow truck is on it's way to take it to the GMC dealer.
The vehicle would stall at idle. First thought it was an alternator problem since the alternator would drop to zero and the vehicle would stall. Put in new alternator. Same problem. Had throttle body cleaned by shop. Problem solved.
Engine nearly stalls, gets to low RPM's in idle and revs start to go up and down as if its stalling and then catching over and over. Then it'll catch on and be back to normal for about a minute and goes back to the stalling.
when in low rpm 1000 the engine quit. When it is started again it start ok, but any time its goes under 1000
rpm it stop.
While waiting for a turn or light, the engine would just die. It may happen a couple of times, although most of the times it just works fine.
Is always running at low rpms while sitting still and will stall at some points
2010 GMC Yukon Denali - The check engine light came on, followed by a traction control warnings and then reduced engine power speed to approx 20 mph to the point of almost stalling. I was told by the dealer that it was the throttle body which I has replaced at my expense. However, after picking up my SUV, I learned that there is a GMC Special Coverage Adjustment for the Throttle Sensor. However, GMC will not replace the sensor free of charge unless you have a problem with it...i.e. ; more traction control loss as well as reduced/loss of engine power. From what I have read as well as heard, hundreds of other GMC owners are having the same problem and GMC knows there are/have been ongoing issues with engine power loss due to throttle body and throttle sensor issues, but they will not issue a recall. I guess people have to be involved in fatal crash before they will do something about it. I will try reporting this to the National Traffic Safety Administration.
Regular maintenance (cleaning) of the throttle body is mandatory on the 6.0l engine.
I am towing a 17 ft. trailer with that weighs about 4K lb. and when i slow down to a stop or slow turn speed, the engine will stall. The problem then continues because the vehicle will not start immediately after. I had to wait almost 3 hours before the vehicle would start again.
stalling and low engine idle hard to start due to dirty throttle body.
Twice now usually approaching stop lights slowing then speeding back up the truck stalls, air conditioning blows hot air, right side speakers fail, no power steering and no fuel injection. This is not a denali. Going to my usual shop Monday to have throttle body cleaned...???
2002 yukon denali stalls at low speeds on turn or backing up, lights would dim, low rpm. cleaned throttle body as described, that took about 15 minutes, now runs like new. power steering pump must have had such a pull on the engine it would stall. i agree should be routine maintenance. thank you forum.
