Question about 1999 Toyota Tacoma PreRunner
The check engine light was on. at advanced auto parts they ran a test and it said fuel too lean so they told me to restart the computer to get the light off. so i did and when i started up the truck it sounded bad and wouldnt do anything i couldnt even rev up the engine. finally it would move. now for 3 days when i get in for a quarter mile it moves slow then kicks in and drives good but sometimes on take off it runs slugish
What was the code? P-0171? If so, you may have a very dirty Mass Air Flow Sensor. This is held onto the intake tube by 2 small screws. Take it out & look down inside it. You will see a couple of silever wires. Are they fuzzy-looking? If so, clean them with some brake cleaner spray. Reinstall, and check for a dirty air filter. Hope this helps
