Answer 1

1150 Lack of H02S21 Switch Adaptive fuel at limit.

The computer can add about 25% more fuel to overcome running problems... once long term fuel trim reachs 25% (works both ways... adding fuel or removing fuel) the PCM
cannot correct the mixture any more and sets the MIL and codes.

So you have a fuel problem. Could be that the pump isn't putting out enough pressure, could be as simple as the filter being plugged. Or it could be something else. So, when you have your mechanic take a look, also tell him about the rear wiper. Chances are it just needs to be lubricated to overcome that friction when it starts.

Answer 2

Code P1150, O2 sensor, bank 2 sensor 1, insufficient switching fuel trim at limit.
May need just to replace the O2 sensor on the driver side, then again, the sensor could be working fine and it is detecting that the fuel mixture is incorrect. That is one of those tricky codes that deems futher investigation to the exact cause. As far as the wiper motor, sounds like the motor itself has a shortage, just go ahead and and save yourself the headache and replace it. It cannot be lubricated, it is a sealed motor.

Answer 3

I would go with the ASE Master Cert on this one.
