Hi,

I have lost my Nissan Altima 2000 gas cap and because of that I am getting "Service engine soon" light on.

So please guide me a site/store where can I get the cap in less cost.

Thanks

I'd say just about any parts store in the phone book/local area can get one if they don't have it in stock (should be no more than $10 - 15, if that much)
Once the cap is back on, just drive the vehicle and the light will eventually go off by itself.
