Hi,

91-740 turbo wgn, 5sp.
The problem is a strong smell of raw gas. The smell occurs constistantly after the car has been driven then stopped (idling or shut off. After sitting for 5-10 mintues the smell is gone. The smell doesn't occur while driving faster than idle.
I can park it in my garage & not have a gas smell when I check the next day.
There is no liquid leak at all. I've been under, over & all around the car. I installed new injectors seals. The smell doesn't come from the gas cap area. Smell is the same pre & post fuel fillup. There is no gas smell under the hood. There is no smell of gas inside the car. The smell is worse w/ the front windows down.
The fuel mileage is un changed & the tailpipe is clean, no sign of carbon at all.
The smell is getting stronger.

What happens when the carbon vapor canister (gas vapor trap)plugs? Anti-roll over valve problem?

Any help is welcome.

Thanks
