Car idles fine but will "choke" when accelerator is pushed.
The throttle position sensor, fuel filters and cadallidic converters have been replaced and/or cleaned out. Don't know where to locate the fuel sensors to replace them. That may not even be the problem; please help and send an email if you know what this could be!!!!! thx. have a new job and will be starting monday june 8th 2009 :(

Do you have an engine light? Throwing a code?
Just does this at idle or when driving/acceleration?
Acting strange changing symptoms (E.G.--idle to acceleration to black smoke out exhaust, etc.)? Plenty of Gas in tank?
I am thinking: No engine light
Clog in fuel filter
intermittent fuel pump problem
A vehicle starting sensor (E.G.--Throttle Position Sensor (TPS))
Engine Light: Pull Code
I would check the voltage on the throttle portion sensor with the engine off from idle to wide open throttle.If there are any dead spots, replace the sensor. If the tps checks out, you should check fuel pressure. If you have good fuel pressure, you may want to make sure there isn't a lot of slack in your timing chain. I don't believe you mentioned the mileage of your vehicle. Best of luck.
Your excellent description provides a very short list of possible culprits, since your vehicle's symptoms all appear during periods of higher fuel demand.
(1) fuel filter - clogged - your description is absolutely classic (especially stumbling upon uphill acceleration) for a fuel filter in need of replacement. (2) spark plug wire - one or more bad - an engine can muddle along while traveling over level terrain with one cylinder intermittently failing to fire, but try to go uphill (even the slightest grade), and the engine will skip badly and can even stall if asked to accelerate. (3) in-tank fuel strainer - clogged - same symptoms as clogged fuel filter.
The fuel strainer is a sock-like pre-filter attached to the input side of the in-tank fuel pump.
The troubleshooting section of the 1998 Honda Civic EX manual states:
Priority Action Part Type Cause 1 Inspect Throttle Position Sensor - Faulty or Incorrectly Connected Throttle Position Sensor. 2 Inspect Mass Air Flow Sensor - Damaged, Loose, or Faulty Mass Air Flow Sensor or Circuit. 3 Inspect Choke - Stuck or Improperly Functioning Choke. 4 Inspect Air Cleaner Tempature Sensor - Damaged or Faulty Air Cleaner Tempature Sensor. 5 Inspect Fuel Filter - Clogged or Dirty Fuel Filter. 6 Inspect PCV Valve - Plugged or Damaged PCV Valve. 7 Inspect Carburetor - Worn, Faulty or Damaged Carburetor. 8 Inspect Fuel Injector - Dirty or Worn Fuel Injectors. 9 Inspect Hose (PCV) - Clogged or Collapsed PCV Hoses. 10 Inspect Fuel Pump - Faulty Fuel Pump. 11 Inspect Fuel Pump - Low Fuel Pressure.
Here's a YouTube video describing hoe to replace a fuel filter on a 2000 Honda Civic (the closest I could find for your 1998).
if your car doesn't even rev up then the accelerator isn't hooked up to the motor. You can check this on the carburetor will be where you can rev it up and if that works then your accelerator is broken inside the car
