fuel pump going out?

[dbsharp]

When I am at low throttle at around 2-3k rpms, the car will sometimes feel like its loosing power and then getting it back, (feels like im moving the gas pedal back and forth). I replaced the fuel filter and that didnt help, also fuel injector cleener didnt help. It only does this while under light acceleration or while mantaining speed. when idleing it occasionaly acts like it is going to cut out but then it comes back to normal. no CEL.

did you check your timing. my bro had the same problem on his 02 lancer and he replaced the coil. check that out.

I just noticed that Ive gone through 1/2 tank and have only 97 miles to show for it.

did you change the fuel pump also??? also do you rev your car up a lot

if you dont mind me asking, what kind of gas do you use? we use premium in my accord, and it to me lasts longer, and the car runs stronger on prem. also if your doing a lot of street driving, it wastes more gas than highway driving. because your stopping and going a lot.

Not always true just wasting money. Good for cleaning fuel system though. 89 should be the max running on an f22a since the premium doesnt do much. For your vibration have you checked your engine mounts? As for gas mileage are your throwing any check engine lights? Thats abnormally low mileage for half a tank.

the vibration is the engine. I will be accelerating smoothly and then all of a sudden the engine will act like its deing and then it starts shaking the car back and forth and smooths out again if I get on it or i get above like 3k. I have no bad motor mounts and no CEL.

[NAiL05]

Does it shake like that when your in neutral and rev it?

[dbsharp]

I havent reved it in nutral but It did do it at a stop sign when in nutral at idle.

Hmm...similar problem a buddy is having with his Talon. The vibration was fixed by replacing the shot motor mounts and adjusting the idle. Still gets horrible MPG and loss of power. Had new o2, fuel system cleaner galore, fuel filter, etc. etc.
Next on the list to check is cat converter and coilpacks, as mentioned above by others. I'd love to find out what fixes it for the OP.

Are you spewing black smoke out the tailpipe? WIres plugs?

[yellaboi]

Had a similar problem with my integra. Turned out to be the O2 sensor.

well since this has been brought back, this happend once in the last 500 miles. It has been going away for awhile and then coming back . I think I can hear little pops occasionaly. Ill be doing a motor swap as soon as I fugure out what im going to do about my transmission, so this might never get solved. if All had gone to plan Id be swapping now but how often does stuff go along with your plan? lol

Dood, not to thread jack or nothin' but could I have your old engine? I like having spares. I'll come pick up...
I don't care if it is actually running or not as long as it isn't locked up...

Lemme know.
