  1. @Morissey I can second Ahsai's recommendation. He is correct... get the Durametric (less than $300 or 2 hrs at the local P-dealer). It will pay for itself in saving you time and money. I purchased one and he has been helping trace the source of the same misfire codes. By measuring actual values, we have eliminated cam deviation, MAF and are now I am going to make a smoke machine out of an old fog machine we used to use for Halloween (and an Ahsai post on another board). In my case, the codes are intermittent amongst the cylinders across both banks but they only happen on a cold start, at i
  2. @Ahsai Thank you... I did the e-gas recalibration and am still getting a slight roughness in the cold start and a very slight hesitation when pulling away in first from a stop... the rpm drop for 1/2 a second as I pass 2k and then comes back and pulls hard and smooth. While researching smoke machines, I found your hack of a fog machine into a smoke machine—Brilliant! I have one and am planning on testing for vacuum leaks this weekend. Still determined to make as many maintenance and repairs on my 996 as I can. I keep telling myself that is part of the pride and joy or ownership. Understandi
  3. Hello... so I'm a victim of marketing. Ironic. My 996 AE is definitely E-Gas as shown above. I'll try the e-gas recalibration as noted above. below. These include the oil temp and ambient temp as requested... you'll see the misfires counting then going away when the throttle drops down to idle. Could this be the purge valve sticking (part no 83-08019561) or would that have shown up in the durametric testing? Going to try and find a vacuum leak with a home made smoke machine this weekend. Let me know if the actual values with the temps show anything new that I should run down. Thank you
  4. Hello again. I'm not with the car... and haven't actually seen the cable for the throttle linkage. I'm only going on what I've read but clearly there are different sources. http://press.porsche.com/archive/products/press_kits/press_kits_2004/PDF/new/1-11_Carrera_Release.pdf Read the first sentence on page 2 of this Porsche Official Press Release.... "This engine is equipped with a direct accelerator pedal linkage that provides spontaneous response and the anniversary car also has a mechanical rear-axle differential that enhances traction and acceleration potential. Together, these chang
  5. Hello guys. "AE" is my abbreviation for Anniversary Edition. Unlike all the other 996.2's that have e-gas, the AE has a cable throttle. I think it was a nod to the past throttle feel. Appreciate everyone weighing on on the thread.
  6. Thanks Ahsai. This model (AE) has a cable throttle so no e-gas present. I am going to try another test with the engine cold in about 2hrs. I just cross posted this on Pelican as well. I've been a long time member there and thought that we might get lucky with some sharing. Will post the updated reports here as soon as I have them. Thank you,
  7. Attached to this message is the archive of this weekends Fault Code PDF files. Thank you again. FaultCodes_Reports_Archive.zip
  8. I don't have the equipment for fuel pressure test or the intake air test. I have noticed that the CEL comes on more quickly as I have been driving again more... I did a three hour drive on Saturday and did a cold start, warm start actuals test. I also am including the most recent faults codes report as it is consistent that the cylinders that are recording the misfires are nearly all of them but are intermittent. @Ahsai can I ask you to look at these reports counting the misfires at cold start and warm start and let me know if these give any additional insights? Thank you! Actuals_Reports_A
  9. Attached here are two Fault Code tests that I ran 1 week ago and this morning before I ran the test above. Note that the misfires are spread across the cylinders and are not always consistent in my codes but I have been throwing these misfire codes for months now and while the car drives strong and pulls hard, I am concerned that I am damaging the motor. Thanks for your shared wisdom and experiences in advance. fault codes071417.pdf Short test 996 070717.pdf
  10. I'm back... cleaned the MAF (appeared clean) and Throttle Body (only slightly dirty)... and checked the intake boots as best I could,,, no apparent cracks or loose fittings. The part number on the BOSCH MAF is 986 606 125 01 Ran through 1.5 tanks of gas with 3 cans of Seafoam. Running clean gas now... CEL came back within a couple of days... Attached the codes report here along with a set of actuals with a hot-start. I will post a cold start based on this text in a few hours. Not sure what to do next besides give-up and bring it to my local independent shop. Was hoping I could trace t
  11. Hi Ahsai. I just put in the seaform. I will take a look at the MAF a bit later and confirm the part number as well as clean it... should be late tonight. I will also clean the throttle body and then report back as soon as I have burned through the tank of gas. Thank you.
  12. That is good news. I'll look for the Variocam timing areas and lift solenoids for any leakage. The gas is less than a week old. The car has been throwing these random misfire codes since I purchased it I think. The coils were so old and cracked that I was confident that they were the source so the continued misfires are a frustration. The plugs/coils I purchased from ECS... the coils: BERU, Mfg Part # 99760210402KT1KT ECS Part # ES#3083524 https://www.ecstuning.com/b-beru-parts/ignition-coil-update-kit/99760210402kt1kt/ the plugs: BOSCH, Mfg Part # 9991702
  13. @Ahsai I must thank you for your time and expertise here. I had some trouble getting good data on a cold engine (getting used to the software and Windows OS as a lifelong Mac User) but attached is a test that I think gets you what you were looking for... it is a cold start and that includes some drive time. The data reports always max out at 1000 rows so that seems to be a hard stop I don't know how to get more data. I also did a visual inspection of the intake boots and the oil filler tube and I do not see any issues with them... When I remove the oil fill cap there is a change in the eng
  14. OK. Got it. I will re-do the test and send you the file... most likely by tomorrow morning. Thank you for your generosity of time and know-how.
