Why my truck stalls out?

Asked by Jul 06, 2014 at 02:20 PM about the 1999 GMC Sierra 2500 3 Dr SL Extended Cab SB

Question type: Maintenance & Repair

When I am stopped at a traffic light or stop sign, brake applied, truck stalls out but fires
up easy after. The only way it keeps running when stopped for lights or sign is I put gear
in neutral then back into drive when ready to go. Truck runs fine when started and in
park. Only does this when brake applied at traffic light or stop sign.
