  1. I did torque then down correctly as I had access to the workshop manual at the time, however having said that it's been to a Porsche Indy who had to remove and refit the plugs to do the leak down test. Still the same issue unfortunately.
  2. I'll have to test the coil wires more closely now as it seems the issue is not a simple one. I'll try dig up a wiring diagram to see what wire is doing what. Thanks for the point on the MAF sensors I didn't realise they are not important at idle. The shop I took it to did test these out and didn't find any faults with it.
  3. Thanks for that fuel pumps were tested and pressure checked to ensure it's getting what it should be. Interesting point about the cylinder grouping, earth points were checked and new ones run for testing. I think I'll need durametric to check the airflow sensors but the shop tested it
  4. Is there any other suggestions on what to look at that hasn't already been checked? Durametric won't give me any additional info that the shops have already seen, so I'm not feeling to confident even if I did have it.
  5. Thanks for that however I purchased brand new coil packs from pelican parts along with new plugs, the old and new coils were tested with a coil tester and they all still work. The car not throwing camshaft deviation faults is the strange one, however I don't have durametric I'm using VCDS which works with this ecu to read faults as it's the same used on some VW's. I've purchased durametric and awaiting its arrival. However the workshops are Porsche specialists and they checked the specifics but couldn't pin point it for sure, other then one thinking it's the variocam adjuster, even in this
  6. Sure, sorry i forgot to add them, the only fault codes i'm getting are as follows which were from a few weeks ago, i cleared them and will have to recheck for codes later today: Random/Multiple Cylinder Misfire Detected - P0300 - 002 - Intermittent Cylinder 8 P0308 - 002 - Misfire Detected - Intermittent Cylinder 7 P0307 - 002 - Misfire Detected - Intermittent Cylinder 6 P0306 - 002 - Misfire Detected - Intermittent Cylinder 5 P0305 - 002 - Misfire Detected - Intermittent
  7. Hey Guys, Desperately seeking your help and knowledge on this one. I have a 2003 Cayenne turbo, the car is running very rough on idle also while driving if your gentle with the throttle it's ok, but when accelerated harder it hesitates and sounds like theres a backfire through the intake. After about 5k rpm it settles down and pulls hard. what i am seeing is multiple random misfire codes from cylinders 5,6,7,8 so it's only from the one bank. This is the only code thrown, absolutely nothing else. I've been to 2 Porsche independents who have both had a look
