    Thanks for the help. It wouldn't start late yesterday and this morning... I jumped the FP relay, and it started right up. Also, I tried activating it on my Durametric, but it did nothing. Am I doing something wrong, or do I have to have to pro version? Thanks!

    Not sure if the last part was clear... is started up again. I drove. When I say I pushed it on the way home, I mean I drove it hard. It felt fine. Should I still test the relay, or should I just wait for whatever it is to just go out?

    I was cruising along this morning about 85 or so and it felt like my fuel pump just cut out. I cruised to the side of the road, engine did not die until I put it into neutral, which is why my guess is fuel. No sounds, no error codes, nothing. I tried starting it back up immediately, and it would not. I called AAA for a tow, and sat on hold of course, so I tried again a few minutes later and it started right up. I made it where I was going and back home this afternoon. I did push it a little on the way home as I'd rather pick the time it dies if it does it again. Any other thoughts? Thanks!

    And another update to this thread... So, after bit, my misfires came back. If I drove a lot in a day, or went on a long drive, no CEL for a few days. Something was still up though. I ran Techron through a few tanks worth and no change.... Was driving me crazy to still see the light. I am sure the other fixes helped, but there was something still going on. I had a enough and took it into another shop I had used before. It want cheap, but he was confident he could figure it out and it seems like he did. He did a smoke test on the intake and found several small leaks and fixed them (loose hose clamps and such). I bet Carlsen Porsche didn't tighten everything properly when they had my engine out for some trans work some years back. The problem started intermittently after their work, but it was not immediately after so I was never sure. Car sounds night and day different at startup now... Hopefully no future updates to this thread.

    Just an update... As of now, I have had no codes nor pending codes for a long time, and normally would have had a code by now. My problem is likely fixed and if it's not, I'd bet any future misfires would be due to carbon build up in my cylinders. The following is all I have done: 1) MAF sensor. I changed this because I read that over-revs can cause it to go bad without a fault code. I got a good deal on Amazon for the exact Bosch part. 2) Fuel Cap. It was clearly old and the o-ring was extremely cracked and dried out. 3) New (and correct) plugs that were gapped at a more appropriate range. The plugs that were in there were Beru 5's and I replaced them with the 6 range in the plugs mentioned above. I've done my best to open up the throttle to clean out the crap, but I have only had one longer drive, so not a whole lot of opportunity to do so other than a few midday ownership of the fwy... I'll post again if there is any future change. Thanks for all the input!

    Those plugs were not very old. 1 year max. They didn't look old in person either (must be the pic), just very fouled (and dirty). There was almost no gap and therefore almost no spark. I scanned the forums for plug recommendations and saw a lot of people like the NGK Iridium plugs, so I thought I'd try that since a local parts store had the one I needed-saw online inventory (BKR6EIX)- and for a good price. I gapped them at 0.032" and that should work just fine. It says the design is for improved throttle response and anti-fouling. We'll see. Yes, the coil packs were very clearly new. I verified they are the newer version (997.602.10400/Beru 0040100036). I took the car for a test drive and was impressed. I did get one misfire at start-up in one cylinder, but that could easily be from the gunk that's in my cylinders (it was #6). Time will tell, but hopefully that's it for this issue. I'll try to repost again with more results. Thank you everyone for any help. Much appreciated! ***Forgot to add in here that a lot or people say the coil needs to "click" into the spark plug. There may be different coil packs, or that may be the original 996 pack, but mine sure did not. I tested with the coil out of the car and examined closely. There is a spring in the boot of the coil which looks and feels like it just presses against the plug.

    So, that gap is what it says in the workshop manual, but everywhere I look says half that. I just got new plugs and installed them. Need to finish putting everything together after dinner I hope. Not much left to do but that was a bit of a pain. It was certainly clear that there was not enough room in those plugs to generate a decent spark. All the plugs were fouled, but the 3 & 6 were the worst. I labeled and kept them all. We'll see what happens after I finish and probably take a few weeks for a misfire again to come up with new plugs! but hope it doesn't. Any recommendations from anyone for an additive to clean they crud out of my unburned cylinders? I am torn on the mechanic. He had an injury and was out when the work was done by his new people. I'll give him a chance to respond to my email and then decide, but I'm not happy.

    I was being lazy and measured it after my post: .018". Had to use a feeler gauge to get in there. That's much smaller than the .06" recommended.
  9. benaslan
    Update to my f'd up thread... First of all, I have had no CEL since replacing the fuel cap, but I did still have some misfires, just not remotely close to enough to even issue a pending code. But, since I still had them, I know it wasn't perfect and wnted to figure it out. Just tore the car apart. First off, solenoid brackets look perfect; no issues there. I pulled the number 6 plug since that one fouled more than any other. It is FUGLY! Not only is it the "wrong" plug and different than I was told was installed (Beru 5LDU versus Bosch 6LDU), but not gapped correctly, or even remotely close to it! So tight I couldn't measure it properly... But somewhere around .015" instead of the book's .06". Any thoughts on the plug choice? I thought Porsche changed the recommended plug to the 6LDU. Clearly the main issue was the gapping, though, right?

    Thanks for all the info! I will post when I figure it out. I can't imagine it's anything major for me. If I have a valve issue, It would have degraded performance, yes/no? This car rocks and all RPM except at cold idle (at which it's just rock-y, haha).
  11. benaslan
    My thought isn't that the plugs would not be bad, but either not tightened correctly, or not gapped correctly. Plugs are Bosch, coils are Beru. The Indy shop I use, the main guy was out when I brought it inand his new junior guys did the work and since I have no way to guage their quality, I have to say there is a chance. Would a bunch of plugs not gapped correctly do it? What if the fuel cap was the main issue and the ECU just needs to be reset. That a possibility?(by disconnecting power and waiting) And yes variocam is obviously a high possibility. I've been tracking the numbers the past 3 days now and while the cam deviation numbers are all within spec, they are all very different every time. I'm guessing that's not so normal?
  12. benaslan
    Yeah, I think I just need to get in there and check the variocam bracket. If both sides aren't broken, then I think I'll replace the plugs again to be sure myself. If not those, then things I may try and have noticed in oth threads: O2 sensor, even though no errors, (although I just did pass my smog test by a mile, so not so sure about that) Fuel filter I'm ruling out major issues since the problem is only at low rpm. Anyone have any idea how many misfires I need for the CEL to go on? Gotten up to 38 on a cylinder and no CEL for 2 days now. If I do go in there for the variocam bracket and plugs, anything elsei should look at or do since I'm there?
  13. benaslan
    64,000 miles. Problem has been around intermittently since around 37,000. Started off just occasional, like CEL light briefly once a month or so, would clear itself. Never any driveability issues. I was told not to worry about it and the part would eventually go out and the problem be known... Now that may happen eventually, but the light is on more often than not at this point and I can't handle it anymore. Still no driveability issues as far as I can tell.
  14. benaslan
    Yes. The plugs and coils were changed assuming that was the problem and it did nothing.
  15. benaslan
    Yeah, I asked the shop a few days ago which ones they used: The coils are Beru part # 997 602 104 00 and the plugs are Bosch part # 999 170 195 90 I am certainly not sure if they were gapped properly, but I'd rather rule everything out before going in there. If only they were easier to get to!
