Well - if you're a DIY mechanic then I'd have to ask just what you expect
anyone to be able to say in answer to the original post? OK - try this on
1) Check your gas cap.
2) If it's not on tight, then read the owner's manual to see how to properly
install the gas cap. Exercise caution as afterall, you are working in the
vicinity of gasoline which is highly combustible.
3) If the gas cap is on tight, then take your car to a garage for further
a "Garage" might screw up the car even worse" - highly doubtful.
why would a gas cap, not properly screwed in cause a "check engine" light to
come on? Call me silly (no, please don't call me silly :)
BUT, I've never heard of that. Fuel pressure sensor somewhere that detects
this? would a bad cap do it?
Not around my neighborhood..:))
Perhaps you mean "garage" as in a "Authorized Dealer"
the last garage I used, was for a cracked main pulley (harmonic balancer)
a week after that, I noticed belt slippage from the alternator, later I
found out they never installed the nut on the bottom bolt!
I re-inserted the bolt all the way in, and installed another nut myself.
I will eventually visit the shop (garage) that did this crappy service, and
give them a piece of my mind. (just a small piece, since ive lost most of it
THANK YOU MIKE
Gas tank pressure has been monitored now for several years. Loose cap -
check engine light. You'd think they'd put yet another idiot light on the
dash, wouldn't you? One that says - "Check Gas Cap". Imagine all the calls
to the dealer...
Certainly a dealer is an option but there are lots of qualified independent
mechanics out there too. At least in the US there are.
I am really BLOWN away from with this info! (figuretaviley speaking....no
last car i had, (before a wreck) was a 90 300ZX. I always noticed a small
burst of pressure when opening the cap, mid to low tank level. However, My
98 Sonta does NOt make this release. Could it be why my dummy light is still
on? (Check Engine light)
Could it be leak elsewhere in the fuel system?
BTW: we call it "dummy lights" around here ;-)
I hate to admit, in South Florida USA, there are LOUSY mechanics! Even some
dealers are horrible.
There has to be good ones, im sure of that, but I have crossed too many bad
ones since my first Chevy, used Monte Carlo 1979 bought in 1981.
I think lack of proper certification by the State, maybe.....dunno....
HUH, whaaaa? i forgot what you were saying???? :))
