it could do whatever it wanted. if they are stopped up then the exhaust isn't flowing. just depends on the oxygen content in the exhaust at that point. just loosen the flanges at the manifolds and drive it. you will instantly know if that is the problem or not.

well when i put the new pump in i probably had 2 gallons of gas in the tank. i went and put 11 gallons in the tank and now it drives perfect! i can floor it or accelerate up to any rpm i want without it cutting off. i guess with this new pump i just need to keep atleast a quarter tank in it?
