Odor of gas? ? ?

My 2001 Honda with 40,000 miles has developed a smell of gasoline. Not
strong to seem dangerous, but strong enough to be bothersome.

This developed during a prolonged cold spell, in case that might have
something to do with it.

The car has been well-serviced from the start.

Can anyone tell me what might cause this?

 

Could need a tune up, checking spark plug gap, timing, possibly valves
not seating properly, run a fuel injection or carbuerator cleaner with a
high octain fuel then take for a long drive. Not burning all the fuel.
If this is not the case then could be cracked lines and or filter due
to water in fuel. I would test by starting vehicle in a dry area, let
run for a couple of minutes, not long enough to warm up, and move the
car, then check the area for leaks, this would tell you if and where a
leak may generally be located. You don't want it to be in an enclosed
area because of the fumes, but a dry area to see what if anything hits
the floor.

 

Thanks Eric -- I'll try that suggestion.

As for tune-up, I had a substantial 30,000 mile servicing at the Honda
agency -- costing $350 -- within the past year. I shouldn't think it needs
any significant servicing at this time.
