Engine issues, and a slow Stealership

[wheelman21]

So one morning in early May I went out, jumped in the Boxster to head off, started her up, and she stutered, almost stalled out, then set into a rough idle. The engine light came on, then started to flash (misfires cyl 1-3 bank 1). Revving to 2k made a loud clattering sound. I shut it down and put in a call to a buddy who used to be a master mechanic at the local Porsche dealership before it was sold off to some scumbag from NYC who now uses the dealership to launder money and move cars through from his other dealerships. This dealership has sense lost it's Porsche dealership and now remains Audi, VW, and M-B. I was also getting a code for a cam shaft position sensor. So on the advice of my friend, I replaced it with an OEM part, and did the air oil seperator while I was at it. After a good couple nights out in the garage, and a sucessful install, it didn't solve the problem. After doing some research and contemplating an engine swap, I decided to take it to the dealer (told me it was a timing chain issue). I trailered it to the dealer on my way out of town for work. A week later, the dealership still hadn't finished the install, and I was going to have to make the 2 hr drive again the next day. :censored: I called the next day, they had replaced the timing tensioner and what not to the tune of $2,300, and they didn't fix it, still misfires 1-3 and clatters at 2k. They then told me their tech is and I quote "stumped" (real confidence booster). So they called Porsche. That all took place on tuesday, here it is Friday and they still have no clue. :cursing: I am not having a good time, and my sense of humor has faded. So can any of you shed any light on the issue, maybe one of you knows something this idiot of a dealer doesn't?

Sorry to hear your misfortune.

What were/are the fault code(s)?

[wheelman21]

I can't really remember the numbers off the top of my head, but they were random cylinder misfire, misfire cyl 1, misfire cyl 2, misfire cyl 3. Camshaft position sensor perf/k

Can you ask the tech that looked on the car?

It is just random guessing without fault codes.

Ok, so the car is back in my garage and running like she did when I first bought her years ago. I wanted to update this, just for future reference for others. So turns out it was the timing chains like they thought, when they reinstalled the tensioner, they had the timing off by a link. Unfortunately they spent an extra week going through the engine, trying to find out what was wrong, went into the cylinders and all. The good news is, they didn't try to charge me for any of the extra work. I was quite impressed with that. Either way, she's all fixed. And the good news is that when they went through the engine, everything looked good. The rings are great, compression is strong, and there isn't any scoring in the cylinder walls, good stuff for 116k. :D
