We have a 2009 Pontiac Wave 1.6 L that intermittently hesitates. The problem occurs at least once a day, when driving between 10 and 60 Km/hr and upon acceleration. The hesitation is as if the engine throttle has been disconnected. I can mash the peddle to the floor with no response. The engine continues to run at a very low idle, then finally responds after anywhere from 1 - 5 seconds of delay. On one occation the engine did die. It seems to be very intermittent. We have had it back to the dealership twice and they say they can't find anything wrong even after test driving it. We have 7 members of our family drive the car and all have expirenced the problem, so it's not driver related. Just wondering if anyone else has experienced this problem or could shed some light on the subject.
Thanks:
