Looking at the recent thread showing tank vent hose replacement, this reminds me of what I found last year.

The photo here shows the vent hose location above the muffler. That grommet had popped out where

it enters the cabin. I reinstalled and then sealed it up real good. That was it. A real pleasure to drive with

the windows down again. Just another thing to check.

Yes, just 1 of the dozen places it can sneak in.

I finally found my source of exhaust fumes in the cabin as well: the hole through which the electric antenna drain tube exits the rear left fender! The rubber grommet had deteriorated. Replaced the grommet, sealed with with black silicone and the car stopped smelling like a muffler.

hey, where is that located exactly? 

Inside the left quarter panel behind the interior plastic panel. Down low inside straight below the power antennae

As seen from the ground looking up behind the rear driver wheel.

The drain tube and grommet is on the right

Where did you find the grommet?

Thanks!

I found a rubber grommet from the firewall of a 90s Chevy Camaro that was an almost perfect fit. Used black silicone sealer to get the rest of the way. Has been working great to this day.
