Re: New gas cap: Does it matter if it's vented?
Im no expert but i think that the fuel system is supposted to be preasureized. Because right after i fill up sometimes my car seens to be a little slugish. IDK.

It will most likely throw a code or "Service Engine Soon" or whatever light you have in a 98. A loose gas cap will do that too. Altho with all you mods who knows?? The system should be under preassure.

Should I assume that the replacement gascap I bought 2 years ago is vented?
My old cap would make a PSSSSSHHHHHHHHHHHH! sound when unscrewed. This one does not.
No codes have been set.
Is there a way to tell by looking?

FI systems are under pressure and require a non-vented gas cap. Thats why you hear that swish noise when you unscrew the cap. So buy a new cap, about $7 at the Dealer.
