Ok the newest problem I have on my 2000 4.4 is that my ODB computer says I have a fuel trim malfunction and camshaft sensor problem. It drives ok but I could tell that there could be a loss of power from take off. Now I think some of that has to do with the AC being on. Has anyone has messages like this before. The car has 73,690 miles on it. I am also contemplating getting rid of her and getting a newer one or leasing a 07 what do you guys think. I would like to fix her if possible.

Thanks Greg
