1999 986 2.5 Boxster. (5 spd)
Not many problems with the car but cruise control doesn’t work and the spoiler only extends halfway or so.
Current actual problem with the car is that I can feel vibration or shaking in the steering wheel (and in the car to a much lesser extent) after shifting into fourth gear. After shifting into fourth gear, the shaking seems to persist even as I slow down, or after shifting into fifth. It will persist even if I shift into neutral but will stop after I come to a stop.
It’s strange to me that this is the case when gears 1-3 don’t have this problem. I am guessing that it’s an issue with bearings or alignment in the front wheels since i’m feeling the vibrations in the wheel but hopefully someone here has a better idea.
Tried googeleing it but couldn’t find what I was after. Was curious if anyone knows what type of flat 6 the 986 boxster has?
Is it a a true boxer engine? Or a horizontally opposed flat V? True boxer meaning it has individual crank pins for each piston and is a true 180degree angle. Thanks in advance
I'm new to the Porsche family.... Just over a month and the proud owner of a 1999 Boxster. It's a project car but still on the road and my point to point ride. Must say, LOVE to drive this car....This one has been lowered some, well alot... and does it hug the road..... Just doesn't miss much being that low.... My question is, I am having an issue with the rear lights on this car... I know I had a problem with the left rear brake light. I tried tracing back the wire but found no problem... I then switched the lamp holder from the right side to the left and all the lights worked... So I thought I had an equipment issue. I bought a (Porsche) replacement bulb holder. Came in last night. Changed out today...Guess what???? Turn indicators work, Backup lights work, Brake light works on the Right Side ONLY, (still) Now no rear tail lights what so ever......I have checked ALL the fuses, only had to replace one and it had nothing to do with the lights. NOTHING has changed....Where did my tail lights go?????? Can't figure this out.......Please help.......Just FYI, ALL the LIGHTS were working as of last Wed. when I did the bulb holder swap and checking the lights. Power is to both wire harnesses. Everything else works except the left brake light and the drive lights. Go figure.......

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?
