RPM issues w/2003 Yukon XL by keisha40

I have a new arising problem. My truck has 59200 miles and now all of a sudden when driving the RPMs will drop and register below zero. With an older car that usually meant a stall. It is due for its 60K mile service. And it is not a daily occurring problem. When the gas was near a quarter, i thought that was part of the problem (ok stop laughing whoever is reading this). But I had 3/4 qtr tank yesterday and it did it again. When i idle it still registered below zero and in park. I shut it off and restarted and then it was fine.
 
Any suggestions

You have to get some carburator-fuel injector cleaner and spray it into the throttle body..It works..I have a 02 Denali and once I did it the vehicle idles fine..In fact I have to do it again..You will have to do it every 3,000 miles or everytime you change the oil...I took the info from one of the guys who post a message concerning this..

2003 Denali XL -- Oh my gosh, my truck memory seat is psycho and does the exact same thing! My rear gate does the exact same thing. They have tried to fix the memory seat over 10 times, not exaggerating. Sometimes it works, sometimes it doesn't. Kinda like my memory I guess!

ObyOne Kanobe-wise one
 
I have a cherry 2000 GMC Yukon, 61K miles and seems the electric windows are failing one at a time. First to go was the left rear and then right rear and then the passenger. Drivers still working. Rear getting clicks in door when you press driver controls or individual door buttons up and down. Passenger will go down from my controls but not up and will go up with passenger controls.
 
Replaced driver control panel, thought it was the lock out but it was not. Speak Obyone so that we all may know.

i just had my 2000 yukon fixed, the check engine light was on when i bought it. i thought it was just a messed up light because it was running perfect. then after about 6 months it started hesitating and jumping rpms at a stop sign........i took to my fav mechanic and he cleaned the throttle body, and bam! light went out, running smooth ever since.,next the back window motors.. ?? i don't think the lady that had it before me ever rolled them down....froze up i guess. anyway hope this helps..

Water coming out rear floor A/C Vent by waitingonyukon

Has anyone had this issue? My son was sitting in the far back (Denali Shorty) and said water was flowing out the floor vent in the back. When I got home I looked and the carpet was soaking wet. Is this an issue of a clogged AC condenser drain? If so, how do I go about clearing it?
