I drive a 2001 chevy tahoe. its a 4.6 v8 and has 140k miles. i have noticed that when i am in a parking lot and i turn the wheel all the way ( to do a uturn) it just shuts off to just the battery. i always noticed that i am only going 2 to 5 mph. any idea why?

You may have a bad IAC ( idle air control) but try cleaning the throttle body first. Remove the intake snorkel, have someone hold the throttle wide open for you and scrub the back side of the throttle plate and surrounding bore with an old tooth brush and some carb cleaner. Be sure to spray some into the small holes next to the throttle plate. That should help stabilize the idle. If it still has a problem, replace the IAC. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ We offer help in answering questions, clarifying things or giving advice but we are not a substitute for an on-site inspection by a professional.

Hmmm? Not sure I understand the notation of the battery?? OK: Many vehicles sense the load of power steering which can be substantial and should raise idle to cover load so you don't notice. If you are really forcing steering at the end of extremes that's not good for it at all in any vehicle. Just a maybe guess and the switch is in high pressure hose on most. Whether it is that or not still needs to be diagnosed, T

The IAC should be compensating for whatever happens to the idle and it's not. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ We offer help in answering questions, clarifying things or giving advice but we are not a substitute for an on-site inspection by a professional.
