What could cause my 94 to be a dog. It just seems to be really slugish, i think my 95 v6 could walk all over it. Its usually off the line that it runs like a turd. the top end is decent but not were it should be. Note the car has a 40,000 mile engine and a new tranny w/about 6000 miles. It has been like this since I got it. Here is a list of everything I have done to it. LT Headers, o/r x-pipe, 1chamber flows dumped,UDP, Adj. FPR, CAI, I have a 75mm throttle body but I kind of question if the sampling tube is the right size(is there anyway to tell?) I have replaced the upper and lower intake gaskets but i used the little rubber things on the lower. i have the svo intakes and 65mm TB waiting to be installed. There is not smog pump or egr on the car. I have the egr delete sensor but i still have a CEL for the EGR so it obviously isnt working. So if you give me some ideas i would appreciate it.
