Gas smell ONLY in cold weather.. ? very noticable
2002 Envoy. 4.2 6 cylinder 130,000 miles
This is my 3 rd winter w/ the vehicle. And when the weather turns cold (30 degrees or less I'm guessing), I constantly smell a heavy odor of gas .
Its driving me nuts ! I m not allowed to park in the heated garage at work anymore because of the smell.
No drips, no puddles, I've been under (not safe) while running with a flashlight looking for gas leaks / spray. Nothing .
The only time I found gas, was about a year ago I had trouble with a coil, I took the large black air intake baffle off to reach the coil. When I did, I found wet raw gas in there. Not a huge amount, but it was wet. I assumed it had something to do with the cylinder not firing due to the bad coil. Thinking it wasn't burning the gas, but doesn't really explain why it was in the intake baffle.
Again, this smell is ONLY in cold weather...
So, what are your thoughts Might explain the 17 mpg it goes down to in the winter months from 18-19 mpg.
I saw on another site something about top of fuel tank / pump leak? Is this a recall that won't cost me anything? I assume test by putting my hand up there (if fits, haven't tried yet).
Thanks all in advance..
