  1. SO, I got a beautiful CEL on my 02 C4S coupe 6 speed with 63k miles on it. After diag, the shop found a misfire coming from 3 cylinders (#4,5,6). The initial recommendation was to change the coils and plugs. So I changed all the coils and plugs on both sides. After completion, the misfire was still occurring with a heavy rough idle, this time, specific to cylinder 6 only. Then, i changed the injector for cylinder 6 (shop recommendation). After the injector, the rough idle was still present with the engine light as well. Then, the shop performed a leakdown test and found gas in cylinder 6. They cleaned it up, swapped coils from 5 and 6 to test proper functionality of coils. The leakdown test did not show any leaks however. SO after this was all said and done, the shop put it in additive, filled up the gas tank, and drove it for 50+ miles or so. The car function properly according to them and I drove it as well, and there no idle, no shaking, no engine lights, nothing. A week after I picked up the car from the shop, the rough idle began again after I gave the engine a little rev. The engine light was flashing, and the rough idle began again. The shop said it could be the lifters for cylinder 6. Any thoughts or anyone here experience similar issues with this? Any help would be greatly appreciated. I would like to gain some knowledge before taking it in back to them and throwing more money at this with no end solution.
  2. 2006 CS Ti. Approx 130,000 miles Recently the CEL came on. My OBDII reader showed misfire for all cylinders (this was on a cold start, so not warmed up yet). Previously it had shown misfire in the ready list so I figured this has been intermittent for a while although the car has been driving fine. No issues with power, hesitation, fuel mileage, etc. So, I went ahead and ordered the coils and plugs and changed them today. Every coil looks perfect. No signs of cracking anywhere. The plugs also looked absolutely fine. What I'm figuring (hoping?) at this point is the coils themselves are failing. See the link for pics. The service history I have shows these were changed at 102,000 miles with the 002 part. The coils I installed are 012. Not sure this is going to make any difference but time will tell. See coils and plugs here.
  3. I am the original owner of a '99 C2, black on black, approaching 60k miles. My Indy recomended oil change and filter, fuel filter, air filter, belt replacement, and it needed a battery. During plug removal, he discovered four or the six coils were cracked! One was pretty bad.; I'm surprised it ran that well. He could only get four Beru's on such short notice. Total damage with labor was less than $1,100, which I consider quite fair. Glad I brought it in, and I'll replace the other two when I get down to FL ( I hadn't been driving it much while it was stored in VA). A few minor leaks from the RMS and on the right side where some sort of sensor enters the engine, but nothing major. I haven't yet done RMS, AOS or IMS, and while I was there his Mercedes Indy friend called and we're discussing the Carrera. His words - get rid of it! Well, I am aware of these issues, maybe they are less so for the early 996s. But I will replace them along with the water pump and clutch at 75 k miles if I don't decide to upgrade to another 'play' car. My Porsche ownership has been wonderful, and I hope all you owners feel the same. Pure enjoyment, a blast on the twisty roads of the BlueRidge Mtns. If only I could get more than 8 k on a set of rear tires!!
  4. 2006 S Platinum with 110,000 miles. Bought the Duratec software and cable. Had a fault on #5 coil back in April, and replaced it. Ran well again for several months, until #8 and #4 showed intermittent issues. Bought 7 more coils and all new plugs, and replaced them all. Wow!!! I thought the throttle response was good before, now she seems to be pulling extremely hard at the reins. What fun to drive, and no idea new plugs and coils could make such a difference. You always hear that plugs, with unleaded gas, will last forever.....case and point, my 2000 Silverado 5.3 at 266k still getting 17mpg and strong with original plugs and wires. I must also offer a heartfelt thank you to those of you who buy new, and give many of us a chance to enjoy these "broken in" machines within our means. Thought I could catch up some day and order my own, but nay, the new prices continue to run beyond me. It is indeed a privilege to take over their care where you have moved up. And thank you, Loren, for putting up with us. Evan
  5. Doing the plugs and coils on my 2001. I know this has been asked before, but the info I have found is inconsistent. I've popped just the plugs in so far and put some anti-seize. Should I pull them and take it off. I've read mixed reviews on this. I also ordered new ignition coils. Do the coil tubes come pre-lubed with grease? If not, should I add some? Thanks
  6. Hi folks, Learning a lot reading through these forums and thanks to all of the contributors. My Cayenne S 2005 had been behaving itself pretty well up till recently and then decided to play silly buggers. Radiator had been coming on intermittently following cold start and last week it a dropped cylinder followed by an emission light warning as the Cat screamed in protest. In the absence of a compression test, I suspect the misfire is either plugs or coils or both so I've ordered a set of each but am open to any suggestions?
