Had this happen once -- where the CEL came on and the gas-cap was the presumed culprit. It lasted for about 2 days and hasn't come back. The dealer had mentioned that it might help if you do a "complete" fill -- versus just topping off. When do you refill?

make sure you get the Porsche cap if you replace.
I had to replace mine after the gas guy forgot to put it back on the car (we don't have self-serv here in NJ). Next day the CEL went on and I stoped by Pepboys and they gave me an aftermarket one. CEL kept coming on with the aftermarket cap.

DJ check your gas cap part #. I know the part has been recalled and maybe it wasn't done to your car(I don't know if this was the reason why it was called back).

^ I think it cuts down on the carjackings.

^Carjackings? Hell, it cuts down on stolen gas!

Doesn't NJ also require police to be stationed at certain road construction work-sites? Or is that another east coast city?

In Texas we chose a slightly different solution to carjackings

I don't really think that's a solution since Texas still has some of the highest violent crime rates in the country.... and you've still got to pump your own gas while looking behind your shoulder.

Actually here in Joyzee you couldn't pump your own gas if you tried. The gas station attendant has the unlocking key card. Once in a blue moon I'll even have the attendant clean my windshield. Close to where I live there are two gas stations a Hess and an Exxon that have the absolute lowest gas prices in the country, rarely over $3 for 93. Yet if you drive five minutes in the other direction this one township has gas taxes that easily tack on another 30 cents per gallon. For the life of me I still can't understand how they stay in business with cheap gas nearby. Must be all the New York drivers who don't know better.
And I think we are also the state with the fewest working air pumps, I have to carry my own.

How does a non self-serv gas station work out? Do you just pull up,give the gas pumperer your card and he does the rest?

Bingo.. just show up and someone else pumps it. It is nice to avoid smelly diesel on your own hands. Plus, NJ gas is "relatively" cheap, and even moreso if you take into account the full service benefit.

I think there was a TSB for the fuel cap and I've seen a few were the main seal on the cap cracked.

When getting gas in NJ, do you tip the attendant at the end?

In 1998 Porsche changed the emission system. The fuel tank is pressurized to check for leaks in all the plumbing. If the the sensor detects a loss of pressure or the sensor is defective then the check engine light comes on. If the O-ring seal on the cap is not sealing well then you can also get a check engine light.

For 1998 up to I forget what year, there was a recall to replace the orange O-ring with a black one.

Then there was another recall for 1998 to I think 2001 to replace the cap with the 2001 style cap. A sticker was placed in the trunk lid for this recall. You should not have the cap that was used 1998-2000.

Don't know what cap you have. Don't know if the sensor is the problem. Don't know the problem until you have the fault code(s) read, unless it is clear you do not have the updated cap.
