Just my two cents, but don't forget to check other things before buying the camshaft sensor.

For example, check the fuel pump relay operation when you try to start the car. If it clicks on, then the computer is trying to run the fuel pump. If the camshaft sensor were faulty, it wouldn't close the relay.

My car didn't start last week. Same deal...it just chugged and chugged but never fired up. I tried it several times during the day with the same results. After verifying relay operation, I checked voltage at the relay, then the fuse. I wasn't getting a ground at either. I checked the fuel pump connections under the battery...still no ground. Finally I opened up the fuel tank, took off the electrical connectors at the top of the tank, put them back on and tested it. It fired right up...I guess it was just not making contact due to corrosion or whatever. Anyway, a week later all is well.

Thanks secretagent214, I'll double check the relay and and pump connections, howevert, the frustrating part is the car will start fine right now, so I'm sure all will test ok. I have never had the car disabled for more than an hour or so, and generally not in the driveway when I could check the above suggestions.

I have been having the exact same problem w/ my '99, the only exception is last Friday, the engine died at 65mph.

To recap, on 7/23 after driving ~25 miles home, I went to run an errand, starter cranked as usual, but engine wouldn't turn over. I let it sit about an hour, started right up and ran fine, next day, similar experience, 25 mi drive, no start, hour sit, started and drove 250 miles that day with many stops & starts. I replaced the 11 year old ignition switch and it continued to start for a few days, then once again left me stranded. I used a P-code reader... nada, but after sitting, she started right up.

I have put ~1,000 miles on since this first occurred. 1999 Boxster w/96k miles.

Fast forward to Friday; driving to work ~65mph, felt a hiccup, saw the dash warning lights come on for a split second, put the car in neutral and all was fine, the car continued running (again, no codes). On the way home, same thing, however the engine quite completely.

AAA towed the car to my house and after unloading, the little SOB fired right up!!!

Can somebody post the Crankshaft Position Sensor part # for a 1999 Boxster?

I've had this '01 Boxter for a few weeks. There are substantial rattles in the drivers door between the inside door handle area and the top rear corner. Banging on the inside door handle or upper door interior with the heel of the hand, road bumps, and sound system bass rattle the heck out of it. I know I have to pull the door panel off to find/fix the problem, but I'm wondering if this sounds familiar to any owners and if any specifc advice is available for panel removal or what may be the rattle culprit.

Thanks much. You guys have been a godsend since I adopter this car.

You may want to check if it's coming from the door latch. Wrap some electrical tape around the loop and see if the problem goes away. If it does, look to see where the tape is getting worn (top or bottom) and adjust the position of loop and see if that eliminates the problem. This is a good first step as it doesn't require any door surgery.

You may want to drop a note to Eric over at Bumperplugs.com. He has a great selection of painted interior parts and probably has instructions for removing and reinstalling them.

Here's on manufacturer that I've seen on-line. No personal experience though.

How do I remove the Air/Oil Separator so I can get at the camshaft position sensor?

Doug_d's DIY on Mike Foke's site is here:

I don't have any experience with this company, but it shows that cockpit covers exist.

I have seen a cover that only covers the fabric top section of the Boxster. What we really need is a factory option like this:

I installed the K&N replacement filter about 3000 miles ago. So far no CEL or other issues - '99 Boxster -62 k miles. It had run the OEM filters until now. I guess I'll keep my fingers crossed.

Thanks for the info!

Looks like I'm buying a MAF sensor. Being new to the 911 community, I don't know the best online sources for parts and equipment. Who's the best?

That's where I bought mine, at the time it was the best price I could find.

My '99 Boxster experienced the exact same conditions, hesitation at ~5500 rpm and same CEL codes. I cleaned the MAF and it got better, but codes returned. I eventually replaced the MAF and all is well, no more hesitation, no more codes. Good luck!
