[snakebitejuice]

What the F***! Many things done to my QX. She stalls while driving nothing over 25 mph. Hard starts only sometimes, then stand for a few minutes and is perrrrring like a dam cat. She has 107650 miles! All check ups have occured, good friend and expert. Oil changes and filter, crankshaft sensor, sparkplugs-coils-boots, pure love_no engine light even before and after problems still occur on regular basis. i have had vacuum leak problem, knock sensor, cylinder misfire, in the past but engine light no longer comes on but taken care of earlier( stalls while driving still) unbelievable!!!!!!!!!Love the QX but DAM====Guys I need your help! This is annoying....URoCk

No check light at all or did your buddy pull the light out lol

If there no code its kinda hard to diagnose, but my guess, water in the gas? bad gas? fuel filter?

Heck it could be alot of things fuel/spark related....

It's worth trying to pull the codes. Maybe the check engine bulb is burned out.And you may see a "possible" code, which won't turn the SES light on until itreoccurs. Check right after you have trouble -- the "possible" will get turned offafter I think five drive cycles.
