91 HF Stuttering and Losing Power

I have a 91 HF which, about a year ago, began stuttering when I give it gas. It would only do it in 2nd gear and only every now and again. It has progressively gotten worse. Now it stutters and has decreased power at all times and in all gears. Is this stuttering likely a fuel filter issue? Fuel pump? Changing the plugs tomorrow. What would any of you vets recommend as a starting point? Besides the plugs, of course, which are due already.

This is not light stuttering. It's pretty bad and is almost constant now.

i would go with the fuel filter. usually (not always) fuel pumps just go they usually dont go slowly.

I have seen a case of a fuel pump going ver slowly over the course of a few months, it was however on an oldsmobile..but it made it run very very lean.

yeah sometimes they go lslow and maybe that is what his problem is. had to tell without seeing the car.

spark plugs, spark plug wires, cap, rotor, coil, distributor, water in spark plug holes, water in distributor, fuel filter, injectors, cam timing off (t-belt)...there are about 100 other possibilities.
Do you have a check engine light? First, I would check to make sure your timing is dead on and that it hasn't slipped a tooth or two. If it hasn't, I would start with the plugs, wires and cap/rotor. Try swapping your distributor with someone else you know that has an 88-91 civic/crx si (same distributor) or another crx HF. If that doesn't fix the problem, try a new fuel filter.

I doubt it's the fuel pump, but i guess it's possible.
