The check engine light will probably come back on, it requires you to drive for about 50 miles for the computer to recognize engine problems. It sounds like you need a tune up. It would be easier if you could tell what the last code it threw was.

Re: symptoms of clogged fuel filter?

A clogged filter is just the same as running out of gas. Not much response from the gas pedal (way down on power).

Re: symptoms of clogged fuel filter?

dont try to fix the misfire untill you fix the crank sensor code first. the misfire monitor test uses the crank sensor to read crank speed, and if the sensor is faulty it can send a misfire code off. fuel filter test..... pull truck into manual one, and let her rip, if you can get it to shift into 2nd on overspeed, you dont have a bad filter, a bad cat, or a bad mass air flow sensor.

I thought that was just from the 4 cylinder underneath the hood.

Re: symptoms of clogged fuel filter?

I recently purchased a 94 2.2L S10 as a commuting truck to keep my Z from bankrupting me in fuel. I'm almost positive i have a clogged fuel filter or a failing fuel pump (if its even possible for a pump to go out and come back to life??) It started by giving me trouble starting on day and cranking up only to die out when i shifted into drive. That was a week ago and the past few days it has only started once or twice after trying severall times throughout the day. Today it was at its worse once started i went for a test drive and it acted as if it was running out of gas i had to pump the gas pedal to keep it moving along. I know a replacement filter is a cheap fix but i just want to get your guys opinion to see if it could be something more like a fuel pump. Also im all about saving a dollar is there a way to clean out filter to get a few more months out of it? any help would be greatly appreiciated...thanks

Re: symptoms of clogged fuel filter?

A clogged fuel filter will almost certainly act the same way at all times. If your truck is hard starting sometimes, and others not, it's not the fuel filter. And once running after hard starting, if it runs strong it's not the fuel filter.

You need to have the fuel pressure checked before you guess as to what to replace.

Re: symptoms of clogged fuel filter?

IT IS NEVER THE FUEL FILTER IN A FUEL INJECTED VEHICLE!!! Fuel injected cars are pushing 40-45 Psi unlike carbs 5-8Psi. Unless you are dumping sand in the tank every fill up. I know it's old but people will see it and read it. The problem is not the filter

Angry Re: symptoms of clogged fuel filter?

see I'm having similar problems but the fuel filter was replaced about a month ago. I also replaced the fuel pump. It ran fine for about four days. But, now it's like I'm running on two cyl instead of four.Also it sounds like something rattling around in catalytic conver. Barely touch the gas and almost no compression whatsover

Re: symptoms of clogged fuel filter?

The converter flow is probably blocked by the crumbled honeycomb inside, that'll choke the motor. Does it idle smooth?

Re: symptoms of clogged fuel filter?

A completely clogged fuel filter will cause a no-start condition.


But a partially clogged filter will cause cutting out when you try to pass someone or accelerate hard.

Labor Rates: $35/Hr. If you watch: $45. If you help: $55 If you tried to fix it yourself first: $95
