What makes you think it is a fuel filter? It does not sound like a fuel filter problem to me, usually if the filter goes it starves the car of gas, it does not usually increase the idle.

what year civic? could be the iacv or ficv (if equipped)

its a 97 civic si (ps im in canada), i hear if the fuel filter is choked it pulls in more fuel when its starving ?

[Greenblurr93]

does it rev when idling?

[Ravi2937]

it revs only when i shift from a gear and put it in neutral, when im in gear and slow down for a light i put it in neutral and roll to a stop it still revs high untill it sits for about 30 secs then they drop to normal

could also be tps
