Hey guys I took the SC in for a smog test today and it failed. It looks like there is fuel that isn't being completely burned at idle. So I went out and bought a new air filter, spark plugs, and fuel filter (Just for the fact that it needs to be changed). I cleaned out the throttle body with some carb cleaner just to get any residue out of there. Any other ideas of what I can do to make sure it passes this next time? I'm hoping I won't have to replace the catalitic converter on the car but if it fails after all of this I may need to change it.
