While driving in 4th gear the car will lose power and begin to slow. Pressing on the accelerator pedal only makes the car seem to begin to stall. Letting off the accelerator and then pressing down slowly will usually bring me back up to speed; but sometimes not. When this problem showed up several months ago, I shifted to D3 and it seemed to abate. It has never gone. The shop said the oxygen sensor is okay, it is 9 months old.

The loss of power seems to also when shifting between gears.

The problem is intermittent, but when it occurs it stays. Yesterday, on a two hour expressway trip, it happened about 1 and a half hours into the drive at about 40-45 mph when the LIE backed up, it had been running at 70-75 mph steady until then.
