#8 of 9 engine stalls at stop
Sep 06, 2011 (8:13 pm)
I have a 05 ext/ls, ocasionaly (2 or 3 time a day) when coming to a complete stop the engine starts to idle very low and rumble and if I don't press the gas peddle it stalls. If I catch it before it stalls and press the gas peddle it hesitates alot before it feels like it gets fuel and the rpms raise. But while moving it runs fine. The check engine light is on and its codes read- fan clutch, fan clutch switch, and o2 sensor. The gas cap light comes on every now and then and feels like it doesn't seal completely closed. Also the 5th speed on my ac unit switch doesn't work but 1-4 do. The rear speakers of the stereo are in and out, usually out. The door ajar and seatbelt chimes are also in and out along with the rear speakers.

I had the same problem. It was like that for a year. I just fixed by cleaning the throttle body. It wasn't hard. I Google it and and found this link. Made it so easy! http://forums.trailvoy.com/showthread.php?t=51619
