Hi all,

i was wondering if any of you can help me identify this problem my 99
corolla hesitates every most of the time i step on the gas as if it not
getting enough gas to the engine. i changed the spark plugs, spark plug
wires, added fuel injector fluid and it is still happeneing. since the
fuel filter is in the tank and is irreplaceable, how can i have my car
stop hesitating when i try to speed up?

thanks
