I get a gas smell inside of the car after driving for about 5 or 10 minutes. I looked under the car while it was running and I couldn't smell anything. I have no idea where it's coming from.. driving down the expressway gives me a headache sometimes. Any ideas? It seems to be coming from the back of the car, but I don't see any leaks.

 

maybe it's coming from your exhaust... check if it's coming from your catalytic converter. You might be running way rich and the cat just cant seem to burn all of it up.

 

The cat is brand new. This is a shot in the dark, but could it be that my gas cap isn't holding pressure? When I take it off I don't get a hissing noise at all.

 

You may as well get a new gas cap for it anyways, one with a gas cap lock, I think they're like 10 dollars from Advanced Auto...

 

I had same problem it was pin holes where the filler neck was soldered to the tank..I found a recall on this and got a new tank for free! i have a 92 t/a and this may not apply to your year model...

 

Does that recall still apply today??

 

IF YOUR CAR WAS INVOLVED, YES. CALL YOUR LOCAL PONTIAC DEALER OR THE GM ZONE OFFICE TO FIND OUT

 

THANK YOU!! lol
