When driving at a constant speed engine stalls. if you push the accelerator down the engine catches back up and may run fine for a while but normally it does this quite often. Throttle position sensor has been replaced, coils, plugs, plug wires, and all injectors have been replaced. When scanned the only code is the one for random misfire.
