97 Max Auto 128K miles.... Problem just started when in reverse if I give it any gas it stalls, will back up fine at idle, no problems in drive, no error codes in ecu. Fluid is fine. Anyone else seen anything like this. Could it have to do with the way the engine twists on it's mounts under acceleration? Moves in opposite direction under load in reverse than in drive.

Any help is appreciated thanks.
