I solved my random dying and won’t start till it’s cold problem....the the crankshaft position sensor. But now the big issue....
Very responsive throttle in park!
But lost responsiveness in each gear up to 4000rpms...shifts smooth yet very sluggish and then WINDS UP and screams like a race car in each gear after 4200 rpms! I can’t figure out why? ANYONE relate???
crankshaft position sensor
O2 sensors 2 front
2000 Boxster S 3.2 manual transmission
I am intrigued. Attached is a photograph of an oil leak from the front of the engine of my 2010 Boxster S. The pics show the front upper and lower oil pan just below the front engine mount when the leak was at its worst. Of course this is the 3.4 DFI engine, the car is pristine and has only covered 33,000 kms.
The history is that the leak was diagnosed as a faulty AOS at the last service a month ago and the AOS was changed. But the leak persisted, not a lot, occasionally a spot on the garage floor but not always. Looking from above and from behind the front seats the engine appeared to be completely dry above the upper oil pan. Also the PDK had become very sluggish and unpredictable when taking off from a standstill but otherwise the car appears to run fine.
When I reported back to the dealer they advised that both problems were caused by the AOS. They said that the new AOS was a faulty part and happily agreed to replace at no cost. This has now been done and after a hot 250 km run the leak has stopped but there is still some oil residue around the lower pan. But nothing like in the attached picture. The dealer advises that this is oil leaking from the intakes left from the bad AOS and that it will clear over time.
Miraculously the PDK is back to perfection so I guess the dealer knows his stuff. But does this make any sense?
My 1998 Boxster suddenly had hot start issues where if left in the sun here in Texas for a few hours would then crank but not fire unless you kept cranking and pressed the throttle. No issues when starting cold. It had thrown some evap leak codes a few times and a secondary AI once but nothing consistent and would also suffer from idle issues if hot start was hard.
Having read many threads I decided that it was not fuel pressure related as in my experience fuel pumps either work or they do not and the same applies to the associated relay.
I read someone blocked off the valve under the lhs air intake plenum and when I did this the hot start problem disappeared but gave other idle issues.
I decided to replace this valve and in the process also decided to clean the throttle body and iacv when I discovered oil in the aos and j tube the aos was replaced 3 years ago.
Having replaced the valve and the aos the car appears to be running better than ever.
I had no white smoke issues or oil cap pressure test problems and the old valve was in the closed position when I removed it so that may not have been an issue.
This whole situation had gone on for many weeks and also gave air leak codes in both banks but using a smoke generator revealed no issues.
Hello there, this is my first post here and I’m writing because of problem with my boxster.
Today in the morning I’ve started my 2002 boxster and noticed strange sounds from the engine/ rear side of the car
It’s a metallic, grinding sound like a loose piece of metal or something like that
Sound disappears when you press gas and comes back once you loose the pedal, I don’t know if it changes while engine is warm
Also, check engine light shown up yesterday, when I connected my BT OBD2 there was no error code.
I came with that to workshop also, and they said it’s a catalyst efficiency error.
I’ve had that error code a while ago, I’ve replaced mass air flow meter and check engine light disappeared.
I think it might be a problem with maf again because I bought not the cheaper, not the original one, but why are there these strange sounds? I’m worried about this. Could it be catalyst this time? Or again should I replace maf? This time I’ll buy original one.
here are two Videos I made
Also I’m sorry if you can’t understand something, my english is not perfect.
Thank you for all replies, I hope we will solve that problem together
I am starting to prepare my car for a track day at Chuckwalla valley raceway at the end of the month, and I was told that the car as it sits has oiling issues? My car is a 2003 Carrera. I bought the car last year with 74k miles and immediately did the following: LN IMS bearing, Waterpump, coil packs, spark plugs, all filters and fluids, clutch + flywheel and a stock AOS. In anticipation of the event, I am going to do an oil change from M1 0w-40 to the Joe Gibbs dt40 oil suggested by Jake Raby along with fresh filters. Is there anything else I need to do to not have oil starvation? Is this issue blown out of proportion? does the 2qt sump extension make that much of a difference? will it affect the streetability? I am running 200tw tires.
