Got this code,

I checked all the lines for cracks/disconnetcs/plugs

Checked that the Drain Valve was operating


I have not got the code again but still whenI fuel up

car starts a terribile missing and as soon as fueling is complete

runs fine. It is worse the warmer it is, if it is real warm car dies

and is tuff to restart.


I am stumped, any suggestions?

The purge control valve could be stuck open. Check operation of the purge valve and try to blow air through it while it is opening and closing.

You could also remove the evap air filter and fill up to see if the filter is clogged. If the symptoms go away, the filter is clogged.
