SlowNA06, I have checked or replaced all the suggestions you gave me with the exception of the fuel injectors and the cat. At 20 mph/2200 rpm it just does not pick up speed anymore. It has that feel of still getting fuel but just does not want to go, but the tranny is not acting like it is slipping and the rpm's won't increase. If I sit in the driveway in neutral or park, the rpm's will get to about 5000. Doing the same in drive or reverse the rpm's will only get to 2200. I think I will try thegipper's suggestion of pulling the O2 sensor and driving it. A guy at work suggested doing the same but then also doing a back pressure test. Thanks guys
