Car stutters at WOT...why?
Car stutters at WOT...why? It idles great, runs smooth but when i go WOT getting on the freeway or going up a hill the engine stutters and jerks alot, i have to let of the throttle and slowly increase my speed.
I have replaced the fuel pump but it did not fix the problem, what else could it be?
Thanks for any help guys!!

well...interesting...i'm just brainstorming, but check some of these things:
EGR valve, Ignition timing, air filter (clean or dirty?), fuel filter (should have done this when you changed your pump). also helps to know what setup you're running.

car is 93. 5.7L Auto completely stock. I changed the fuel pump, fuel filter and cleaned the air filter. I just added some fuel system cleaner this week to see if that helps clear anything up.
