Hi,
I had an unusual problem with my 240 wagon the other day. I started to
smell gas fumes inside the car while driving. There were no apparent
leaks anywhere that I could tell, so I was going to check the o-ring
seal at the in-tank pump, thinking maybe it was bad or something. Well,
before I got to that, I stopped to fuel up and when I went to take the
gas cap off, it just came right off, clearly it had not been on right. I
guess I must have been distracted when replacing it. So it occurred to
me that this could be the problem, and apparently it was, because after
closing the cap(clicking it a couple times as I usually do), and then
driving off for a few miles, no more fumes.
I guess this is a closed, sealed fuel system in order to work properly.
A friend of mine said he had heard that, on newer cars, if you don't
close the gas cap tight it could cause the service engine light to come
on. I had never heard of that before.
