1993 Chevy Cavalier 4 cyl Front Wheel Drive Automatic
Charcoal canister vacuum line to purge vale
has fuel in it?
Removed the Canister line that I believe returns to tank:
it too has presence of fuel?
Purge vale: using vacuum tool. Will hold a vacum.
with no vacuum present: DOSE NOT allow flow
with vacuum applied: allows thru-flow
this was preceded by. Presence of ethanol smell in passenger compartment? With engine off and while removing fuel tank gas cap: I WAS SHOCKED how much pressure had built up in the tank? IT took some seconds of tine for it to relieve itself?
Earlier in the day. I had removed the charcoal canister
to blow through w/ low pressure to check flow?
[REASON for this has been a rough IDLE in drive.
drivability enhanced by shifting into neutral at stop lights (the idel roughness will continue to worsen if left in drive-)]
observed vacum hose at port to purge vale slightly collapsed. Figuring incorrect hose material IE non-gas approved.
SO the main matter is this tank pressure and fuel in the line presence?
have the same problem?
