2005 Pontiac Sunfire: 15,000 miles - driven 3-4 times per week - usually short distances 2-10 miles - a little freeway driving. When I come to a stop, then press on the gas nothing happens (car remains at idle rpm of about 600) ...or the car bucks forward a little.
Sometimes I can get the car running again by pumping the gas pedal. Rarely the car stalls. If the car does not stall,I generally have to turn off the car and restart the engine. Car then runs fine. The problem generally doesn't occur again for a couple months, but it has hesitated after stopping two of the last four times I've driven it. It only happens after coming to a stop.
Engine can be cold or fully warmed up. 'Check Engine ' light does NOT come on. I tried using high octane gas. That seemed to help for a while, but now the hesitation happens even when running 81 octane gas.
