I recently purchased a 1994 Firebird. I was driving last night and I opened
the window a bit, and there was a noticable smell of gas. When I closed the
window I could not smell it. I later parked the vehicle and noticed there
was a general smell of gas around the exterior. I started to clean
something near the rear driver side wheel, and there was a more intensified
smell which seemed to be coming from the rear area.
Any one have any ideas what this might be? I topped up with fuel earlier
that evening as well.
My '94 Firebird has the same problem, whether the tank is freshly filled or
not. Everything on the car is dry and seems normal, but when I open the
window on the highway I can still smell the gas. I don't know what the
Thanks to everyone who responded.
I took the car in this weekend for an oil/filter change. I got them to
check for any leaks or cracks in the exhaust, fuel lines and gas tank, but
they could not find anything abnormal. I ended up getting a 4 stage fuel
system service for cleaning and conditioning injectors, with throttle body
cleaning as well. The smell seems to be much less noticeable now, and
actually I didn't smell it after I parked the car either.
A friend of mine who is a mechanic for GM also told me that it could simply
be old gas sitting in the tank for a while (I just bought the car, so I
don't know how long the thing was sitting in the dealer's garage). He
recommended I take it on the highway and drive it hard for 30 minutes to
clear out the older gas.
Could also be the fuel reclaiming system canister. Your friend should have
stated right away. Also, do you have a 3rd gen? The filler neck has a
somewhat common flaw of breaking at the tank and leaking. A GM tech should
know that as well. 2 cents.
I missed the first part of the original post..
Recall on the fuel tank. Bad welds on the filler necks.
Overfilling with fuel and the purge tank is filling with a bit of fuel, you
will smell it for sure then.
