Re: Failed Emissions, need help
err.. when you get it figured out let me know, im on the same bus to crapville. so far i replaced plugs, wires, cap, rotor, pcv, o2, and egr (have k&n for air filter, it was time for a tune up anyhow) i was told that a vacum leak causes a just failed situation in carbohydrates? but i can't find mine. so share the info once you get it figured out, and ill do the same if im first.
in any case, ive been told numerously that platnum plugs don't work all that good in a truck motor, stick with some kind of truck plugs.
