Fuel Supply System b20b/pr4(obd0)

[JDMirza]

Im throwing this code, and sometimes my car keeps idling from 1k to like 1.5k and then sometimes its set at 2k. my question is that my fuel pump is bad or my fuel filter is clogged up one of the two ? It's a 91 hatch dx with a b20b in it, pr4 ecu. I'm throwing code 43, which is fuel supply system.

i would say check your fuel filter first. gettin crap in it will cause your car to idle all funny like that. if it aint that could be the fuel pump. how lond has it been since you last changed your fuel filter?

[JDMirza]

It's got 129,000 miles on it, i bought the shell when it had the old fuel filter when it had 123,000 miles. It had the fuel filter and the fuel line, just no motor.

so it has 6000 miles on that filter right?

so it has 6000 miles on that filter right?
No, current mileage on it. The filter has never been replaced, I bought the shell the filter was already there with the fuel lines just no motor.

129k? Your lucky the filter even flows if it OEM. Replace ASAP. A clogged filter put a lot of stress on your pump also.
