i have a 91' integra LS and the other day after i filled it up with fresh gas it started sputtering when driving it.

EXAMPLE:

When i am at a stop light the car will sometimes die or when taking off die and it will struggle to get the rpms back up to normal once i have a good enought rev (4500) i can take off. I am pretty sure that the fuel filter is whats bad but i just wanted your guys opnion.
