About 165K miles. Fuel pump/filter replaced. New Plugs & wire set. MAP sensor replaced. Dealership can't find problem. The vehicle stumbles out of acceleration from a stop and when attempting to pass on the road. After a few seconds the RPMs increase and car comes up to speed. Very dangerous when turning in front of oncoming traffic.
