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. -
Hi Porsche enthousiasts! I am reading a lot since a few days on these forums, especially the 986 ones there i am a fresh owner since march of this year. There my Boxster is driving perfect i am wondering about a weird noise at cold startup and sometimes but not often after a restart after e few houres of driving. I have already asked this at two Porsche specialist over here but none of them are able to tell me exactly what it is. The only thing they do telling me is not to worry about and to drive the Porsche wihout sleepness nights. The first one is sure that the noise is well know also on the 996 engines and will not go away and not will harm my engine eighter. The second one thinks about the timing chains but also, nothing to worry about. I don't now what to believe or todo with it. I want to know where the noise is coming from so here is the link of a soundclip attached. The noise is on the driver side and at cold startup for a few seconds, than it goes away and my car is running perfect. Hope someone can help me over here. Thanks a lot guy's !!
