Alternator is all fixed! I might be imagining things but the S4 feels a lot stronger. Maybe the old alternator was working hard to produce voltage and taking away some power from the engine. I don't know. Anyway had to re-align the fog lights since they were a little off because the bumper was removed. I think I might have some good help for feature project (see left). My daughter is only 1 (21 months) years old and she figured how to help me install a fog light after watch me with the other one.
Anyway, all that is left on the repair list is a possible EGT Sensor and replacing the injector gaskets as one of them has a vacuum leak. Not looking forward to that one as it takes forever to removing the fuel rails, but I've done it before when replacing the Aux Water Pump so hopefully it will go faster.
