i changed the plugs and wires today and they were caked too. Funny part is after i changed all that stuff, i reset the ecu and now the a/f guage is marking lean. so i might have fixed my problem. ill know for sure tomorrow when i take it for inspection again.

Is it saying lean at idle?
Yeah those things you mentioned will definately cause problems.
