Hey guys I gotta make this quick before I run into class. So I pull in the parking lot turn the wheel my truck dies. I restart it go around another turn it does the same thing and then twice more before I get her parked. I just replaced the intake manifold gasket with new green one two moths ago. No codes at all. 99 silvy z71 5.3 4l60e. CAI, lt's, 3 inch cat back, electric fan swap. What do you think is goin on? I'm wondering if my alternator (110) can't keep up with the fans? Would that cause it?

 

Mine did that crap the other day i was backing into a parking spot at idle and my tires touch the control arms very slightly when turned completely and mine stalled also. My buddies did the exact same thing the other day. No codes no nothin. O well lol.

 

My 2001 Silverado with drive by wire used to have similar issues in a parking lot or coasting through a u-turn lane. Took the throttle body off and found that behind the blade it was all gunked up. Cleaned it well and reinstalled and the problem was gone.

Doesn't mean this is the problem on your truck, but it's worth taking a few nuts off and checking your throttle body to see if the blade is sticking some.

 

What was the weather like by you? Mine only does it in cooler temps (30 and below) it was 25 here this morning
