Last week the check engine light on my y2k QC came on and stayed on. It was
running fine, so I figured a bad sensor or something. I knew about the
loose gas cap issue (if the cap isn't on tightly & sealed, the low pressure
in the tank causes the check engine light), but I discounted that as I
always tighten it firmly.
Took it in today, and the dealer did a smoke test with a smoke generator..
it was indeed the gas cap leaking.. and it was on tight.. heheh.. faulty cap
they say, they replaced it and all is well..
