So far I replaced the gas cap, the selenoid and the charcoal cannister. Still, I can't pass inspection because of the cel, can someone supply me with another remedy?
Proper diagnosis with a scan tool capable of running necessary tests and possibly the use of a smoke generator.
DIagnosis is different from 'scanning'. CHECK your state laws (DEQ?) so you DON'T waste money on guessing. Those suggestions are the 'other remedy' you requested.
