Hello, I'm new on this forum and stumbled upon a new problem (or old) with my 2.5l 986 Boxster from 1997.
The problem occurs when the engine is started dead cold after sitting a few hours/overnight.
Engine starts immediately but the RPMs start to surge / hunt between 1100 and 700 RPM. This continues for about 10 seconds after which the idle smoothes out to the normal cold idle RPM.
The first pull away requires a tad more throttle then normal to prevent stalling. After this first pull, everything is almost normal and engine performance becomes better and better. When the engine is hot, the idle sits at 780 RPM with a minor fluctuation now and then (seems to be more than normal)
I've been to two shops (official Porsche dealer and local Porsche specialist). Porsche dealer couldn't find anything and the specialist found the camshaft sensor on the left bank to be unplugged - but now comes the strange thing - the cabling is nowhere to be found!!!!!!? Took the car home to check myself but didn't find anything.
No camshaft related codes to be found in the diagnosis and no CEL either.
Attached one pic showing the sensor and it's missing plug
Could someone help me out? - Is it possible for the engine not to throw a CEL when sensor is disconnected? - where is the sensor wire to be found?

Help - i have a 2003 Boxter tiptronic s - in great shape other than a shrill loud noise like a Kazoo that only happens above 78mph - it sounds as iff coming from around the mirror area of the windscreen but then occasional sounds like its coming from the speaker area passenger side - that being said could be sound transference. Read a number of blogs about badly fitting windscreen so put tape over top rubber seal and body but still there - - as a say like a kazoo at 78mph with hard or soft top - absolutely driving me mad - any help gratefully received.
I just bought myself my first Porsche, a 1998 Boxster. I have an issue with the soft top that I'd like to get some guidance on.
The top goes down smoothly with no issues. It also comes up smoothly until it is nearly all the way up. Just before the dashboard Top light goes out, there is a pretty sharp metallic twang or snap. It did this when I was looking at the car before purchase, and it did it again this evening when I put the top up after driving the car home. I'm assuming it's getting caught on something but I wonder if anyone might have suggestions on what to look at given the late point in the cycle where it occurs?
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
Hi guys. My car wont crank and i dont know why.
On the start lock relay there is no permission signal from the ECU. Directly starter will cranks and engine work.
I have fault code on bracke switch, but brake light work. And driver seat airbag.
Please help. Sory for my English.
