Definately change your fuel filter. You should only be putting 15000 miles max on the fuel filter. that will most likely fix your problem.

I would just worry about the fuel filter. Fuel filters do cause shifting problems and is most likely the cause of your problems.

I don't think so. Those are electrical communication trouble codes. Weak batteries could cause it or they could just be hicups in the programming.

You should always replace them in pairs. That way when the other one goes it doesn't kill the new one.

I don't keep track, but when I was new on other forums, I had some real newby questions too. Sometimes the simplest things are overlooked or not known to be looked at. That is why I enjoy these forums, you can get answers to just about any questions. This forum is still pretty new, so there isn't a whole lot you can do a search on. Besides, everybody has there own way to describe the same problem.
