Chevy service engine soon light

Engine problem
2000 Chevy S-10 6 cyl Four Wheel Drive Automatic 90000 miles

Received the Service Engine Soon light and hooked it up for a diagnostic test. The codes gave a fuel too lean indication. Replaced the fuel filter and light disappeared. However, it has come back again and the computer is giving the same message of fuel too lean. What shall I do?

If you can post the code it would be good, until then You may have a vacuum leak, get a can of spray gumout, spray the vac lines and maniflod area, when the idle changes, youve found the leak! You want the engine running and spray on the outside but do direct the stream onto the hoses, if it is a vacuum leak, the engine idle will change speed, then you have detected a leak, repair the vacuum leak and see how it runs! Also check the air induction plenum, any unmetered air will cause this.
