i just got through this similar issue. im w/roger on this one. plus he's really helped me so i know he knows whats up. now the question i have is that when you accelerate is it bucking and slow to red line hesitating the whole way? does it do it when the gas is low or at half or all the time? my issue was the pump. if this is the case, BAT sells the pumps for $75. find out what screen you have b/c that was my problem. i had the wrong screen and it made it worse. my car runs great now that ive done this. i dont have a screen on the pump but have the one on the bottom of the pump housing and its working good for now until i can get the right screen. fuel filters probably not it. way to check that is to ride at about 30-35 mph and put it in 5th and floor it. it'll bog down but if it sputters then the gas lines clogged meaning replace the filter. if it just bogs down but no sputter or hesitation then its not your filter. just some thoughts........
