2002 Chevrolet Astro Question: Check engine light



deetee, 4.3L V6, Glen Ridge, NJ, September 23, 2010, 19:38

This van is not getting enough air in the fuel mix. When the check engine light comes on the fuel efficiency goes in half and it uses a lot of oil. I replaced the air flow device and some cables.. It did n't help. The light comes on after the engine is warm and after I fill up with gas. When the light is on the van will occasionally run rough

    What OBD codes are you getting? It's possible you have an internal fuel leak.
