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?
My A/C has been getting warmer over the last week to the point of just warm air. The compressor is engaging as I can see, hear, and watch the tach drop slightly as it does. I figured it just needed a quick recharge, but the low side pressure is ridiculously high at 90psi. Before I go and pull the world apart does anyone have experience with this scenario? Does this point to a bad compressor or Refrigerant Control Valve? I'm not really finding anything in the search dialog.
I have a vacuum and used it on other cars, but have never seen this "overcharge" high pressure issue. I guess I'll try to lower the pressure first, but I have my doubts it will fix anything.
Thanks in advance for any input.
Hey everyone, i own a 2010 porsche Boxter 2.9L with the PDK transmission.. yesterday after leaving the car for a 4 days i started it and went for a drive.. when i turned it on again, i got a warning message “emergency transmission run” and the car became very jerky through gearshifts and wouldnt accelerate properly.. after turning it on and off the message went away and it drove just fine but then it kept re-appearing mid drives and becomes very jerky and clunky...ive noticed since i had the car that the gearbox was sometimes clunky or would make a noise when changing gear but the dealership said that was fine and normal since its a PDK, the car is at 59,000km so its time for a transmission fluid change... could this be a low voltage problem, or transmission fluid? The reverse gear works just fine.. has this happened to any other owners?

I have racked up 15,000 miles over the last 3 years of ownership. The coolant was flushed about a year prior to purchase. I think it's time to flush the coolant. I plan to buy the Airlift tool - it's a time vs cost issue, time wins.
I know from searching that JFP has recommended to others to replace the water pump as preventative maintenance on a car this age. Fair enough. Porsche pump, clean the mating surfaces carefully and:
1. Use gasket sealant or no sealant?
2. Should I replace the coolant reservoir even though I cannot find anything wrong with it?
I'll replace the thermostat at the same time.
3. Should it be the 160 degree thermostat?
3a. I notice that the car runs between 190 - 210 degrees (using Scangauge) most of the time in warm weather, so will the 160 stat be a benefit?
4. Which hoses should be replaced?
5. Anything else?
Since the start of ownership I've done mostly preventative and general maintenance with very few actual failures of any kind. With that being said, I think mileage is beginning to expose some common failures cropping up like what happened yesterday - the turn signal stalk won't hold in-place, so now I need to replace it but at least getting the 4-stalk version will give me the OBC functions.

Me and my dad have recently bought a 2001 Porsche Boxster that has not been run in 2 years, as a "fairly easy" project to start with. So where to begin we did all the basics for a car that hasn't run in 2 years, we replaced the spark plugs and tubes, so then when we tried to throw some gas in it wont let us, we have checked the E6 fuse as was suggested on other forums, we slowly threw in some gas at a time, about 5 gallons in total. When we tried to start it it didn't, so when we tried to troubleshoot we found that it has no spark. So does anyone have any idea or suggestions on how to fix any or all of these things?
