  1. Thanks for you reply. What do you think if i put my original cats back and test the car? Btw i store my original cats in my storage house out from the box, any problem with that? How i know if my original cats are broken inside?
  2. Is better to change the o2 sensors before changing the cats? The porsche factory was working on my car for 2 weeks now:/ didn't check the o2 sensors?:( they said something about the pressure and the ecu reader, and also said that these cats had bigger tubs than my original.
  3. Hi all, They clean my injectors. The problem is still there. They say me that the problem is the low backpresure due to the 200 cell cats 63mm. Is that possible?
  4. I have exactly the same problem. Hesitate at low revs. My local service shop said that i need to replace the fuel injectors.?!?
  5. Do you think is good idea to try fuel injector cleaner before to change them?
  6. Hi all, They call me today from my local porsche garage and said that i need new fuel injectors and fuel pump due to the reason that the car was sitting in the garage for 2 years the injectors are daged and is the reason for the misfire.!?!?
  7. Do you know any website that sell used original cats for my car? Btw i forgot to mentioned that the car was in my garage for almost 2 years with flat battery.
  8. My vehicle sustained an impact at the rear end. The local porsche garage said that i need mufflers and cats. I bring the car to another garage and he said me that my mufflers it was fine (no damage). And i only change the cats. Because the original was 2,500 euro each i decided to purchese the x pipes 200 cell 65mm from designt tek. For only 700 GBP. I have no idea what to do:/
  9. Thanks all of you for your reply. I will bring the car to a porsce dealer. Btw the car has only 45000 khm. So you beleive the problem is not with the 200 cell catalytics, due to the low back pressure?
  10. Hi, Loren, Engine light turn on today. I scan it with my lemur bludriver and found the error: P0430 Catalyst System efficiency Below threshold Bank 2. Is that code have to do with my misfire? If yes why the engine light turn on today and not from the day tha the problem Start?
  11. Hi, Error code P0004 terminal 50. Anyone know about this code?:/
  12. Hi, I bought x pipes 200 cell catalytic converters for my 06 997. I have a problem with the back pressure. Misfiring at low revs when accelerate. I have 02 996 catalaytic converters and am thinking to install it on my 06 2006 997. Do i need any extra parts to fit them?
  13. Hi Thanks for your reply. The scanner only said "Comunication instrument cluster" :/ i will scan again on monday. I notice today that the problem start when the engine temperature is at "80". Below 80 all was fine i think.
  14. Dear all, Im new to the forum and i have a problem with my car. I have a carrera 997 2006 model. I didn't use my car for the last one and a half year. Last week i change the battery and also i changed my catalytic converters. I install 200 cell sport catalytic converters 63 mm tubing. I notice that the car bucking/misfire at low rpms. For example when i have 3rd or 4th or 2nd gear and the rpm is around 1.500 and when i push the fuel pedal (accelerate) the car bucking (no check engine light) for 1 or 2 seconds. If i push full the throttle all is fine. In high rpms everything works fine. Any
