Default Re: Rough starts on Cool/Damp days

As unbelievable as it may sound. I replaced the PCV valve, and my rich fuel code has not returned. The list is long so here goes:

pre cat replaced
rest of the exhaust system checked, no restrictions
timing checked and verified good
fuel rail and injectors removed and checked (twice)
new 02 sensors (both)
all other sensors check with scanners (three different shops) and one friend
new air filter
new plugs and wires (NGK plugs/wires-best the parts store had)

I dont believe the coil pack have ever been removed. Thanks, Basil

REWARD EXCELLENCE!
