Not related. The service engine soon lite is operated by the speedometer, so it's just coincidence that it came on soon after the water pump repair.

When removing an engine from any automatic box the best tip is to remove the bolts holding the torque converter to the flex plate/flywheel and leave the torque converter in position on the shaft in the front of the box. It will move back to the box enough to separate the engine . Turn the engine around to get to each bolt. If the transmission is going to be unsupported then restrain the torque converter with a plate bolted through a flange hole or a strap across the front a note here is that what you call a skip loader may be known as a skid steer loader in which case there will be no torque converter as it hooks directly to a hydraulic pump via a splined shaft.

I wild have to work on this until I duplicated it, then check the vehicle while it was messing up. You could have one defective component even if you just replaced it. (Fuel pump, ignition module, crank sensor, etc.) You could have simply a bad coolant temp sensor, or maybe your mass air flow sensor causing problems. You could try unhooking your coolant temperature sensor and seeing if it wild start. This makes the pcm look at a default value. You can try the same thing with the mass air flow.Do you have access to a scanner when it is messing up? Have you checked for spark at the plugs? Have you checked your fuel pressure? Sorry, I would have to actually work on it.

front or rear?
nice guess, huh? asking for something, never seen, or shown

why not ask why, it does this an not guess.
this car has a 1 wire wiper motors.
that means all actions are the reults of this,,,,,

windshield wiper control module , WWCM?
so it its bad.
or its inputs are wrong. (logic)

there are only 2 inputs from the Multifucition switch
if they are wrong, the wiper will fail
if they are correct then the WWCM is bad.
