2000 Chevrolet Malibu Q&A

2000 Chevrolet Malibu Question: check engine light PO446

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? -
Answer 1
Proper diagnosis with a scan tool capable of running necessary tests and possibly the use of a smoke generator. -
Comment 1
The vehicle was scanned this morning at a state inspection station in Cape May. -
Comment 2
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. -
