Should be ok 'til Monday, but I'd limit it's use so as to avoid the CEL.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

23 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

The gas attendant forgot to put the gas cap back on my car, and I can't go back to the gas station. Do you know if an off the rack gas cap will fit? If yes which one? What is the danger of driving without a cap until the replacement from Porsche arrives on monday? Thanks

POST 2Original post

Eventually not having it will fire off a Check Engine Light. Not having it tells the emissions system that there's a leak in the loop. Other than that, there's no real danger. Don't know about an "off the rack" fix. Should be ok 'til Monday, but I'd limit it's use so as to avoid the CEL. BTW, it's OK to tell us you left it off....we all have senior moments!

POST 3Original post

You must not have the cord that attached to the cap so it hangs? Saved me many senior moment times!

POST 4Original post

You might as well go for the $40 plastic aluminum look gas cap. You really have to file that under "what's the point".

POST 6Original post

Dont use the off the rack cap. I did and the CEL came on. Must use Porsche cap.

POST 8Original post

I'm sure you can get one at one of the porsche junk yards for cheap.

POST 9Original post

I got the Tequipment cap recently. If you want I can let you have my original gas cap for free. Send me your Fedex account number or mail me a prepaid envolope. John

POST 10Original post

I can't believe you admitted to purchasing that cap Just kiddin of course. But, you most post a pic of it on your car so we can all see that beauty of a gas filler cap.

POST 11 / ORIGINAL POSTEROriginal post

Thanks for your responses. My dealer sent me a new gas cap over the weekend. It turns out that my original cap was not attached to the car which is probably why the attendant (NJ only has full service) forgot to put it back on, the new one has the rubber cord which i can now fasten to the car. (I bought a used '99 996) My CEL is still on, do you think it will eventually go off by itself or does the computer need to be reset?

POST 12Original post

Do you have an OBDII reader? If so you can reset it. They can be had for under a $100 and are a great tool to own. Also, you can go by your friendly local AutoZone, etc., and they will read it for free and clear it. Just get the codes if you do have them do it so we (if they dont) can explain them to you. Best of luck!

POST 13Original post

I am embarrassed to admit that I did in fact succumb to mod fever and purchase the Tequipment cap. It looks really nice--so nice in fact, that the next mod will have to be a lucite replacement for the tank filller cover! Perhaps a mini version of the transparent rear decklid on the latest Ferraris.....(Eric bumperplugs, do you hear me?)

POST 15Original post

Actually I've been thinking of doing this mod. When you send the pics, please do a tech writeup on the install, along with various pictures throughout the process, of course!

POST 16Original post

All kidding aside, how do you attach the rubber strap to a 99 C2? I cant find a place to attach.

POST 17 / ORIGINAL POSTEROriginal post

I also cant find where to attach the rubber cord for the gas cap.

POST 18Original post

Cars prior to 2001 do not have the proper hole for the plastic rivet at the end of the tether. So this is where you put it.

POST 20Original post

Here you go--sorry about the picture sharpness, but my camera had an off day...

POST 21Original post

I don't think it was the camera. I think you were shaking with excitement to see it.

POST 22Original post

You just made my morning! I'm here laughing out loud!!

POST 23Original post

Unfortunately, this is true. The seal is very important for the emissions control system. Good luck. Chad
