Well, after some thought Im going to replace the fuel filter. After owning the vehicle for 2 years I ran the fuel lower than I have ever ran it just 2 tanks ago and the fuel light came on for the first time which is about the same time I started feeling the bumping on the freeway which I thought was a cv joint. It only happened when I was putting torque on the engine so Im guessing that is the most likely and cheapest fix. Thank you to all of those that viewed this page but did not bother to answer. I will be sure to take any further questions to some other site from now on.
