  1. If the air fuel ratio was corrected, yes, these would clear themselves.
  2. He just might surprise you next time around..................
  3. Almost; in your state, the use of aftermarket "universal" cats will fail your inspection program, they have to be factory. The sensors will work fine, but the use of aftermarket emissions component's is a no-no.
  4. Depends upon which faults, but yes, the DME can clear codes all by itself after a repair.
  5. Pedro overcharges for a kit you can make up yourself for a lot less. You do not need a permanent oil pressure installation, most decent shops have a test gauge for just this purpose;
  6. Not really, as long as the cat is doing its job, it should make no difference.
  7. What is your oil pressures doing during the cold start, hot idle, etc.? There was a notice about excessively low oil pressure at low RPM's, along with a simple fix kit (new oil pump spring and piston).
  8. The quickest, and probably easiest as well, method to disable the system entirely is to disconnect and plug the vacuum lines running to the vacuum chambers on each side of the PSE under the car. Vacuum is used to close the valves, making the system quiet, unplugged, it will be forever in the loud mode. Enjoy 🙂
  9. Actually, it was the Swiss market that led to this. Factory installed PSE will automatically go to the quiet mode between certain KPH vehicle speeds to spare the neighbors ears. Normal behavior unless you defeat the control system.
  10. Porsche sells an very well made cover for the car.
  11. Not at all strange or unusual. “Fecal matter occurs” and all that.
  12. You need to find out if the injector on that cylinder is stuck open, probably the easiest way it to monitor the engine off fuel pressure to see if it drops off due to leakage. You need to address this quickly as the unburnt fuel will wash the oil off that cylinder wall and lead to scoring. Once you fix it, change your oil and filter as the oil will most likely have a lot of fuel in it. Good luck!
  13. Your engine off fuel pressure is out of spec low (3.3 bar, spec is 3.8+/- 0.2, so the low limit is 3.6 bar). You may have a regulator issue as the running pressure is also at the lower limits.
  14. P1123 ands 1125 are bank codes for an overly rich condition, common issues are leaking injectors and fuel pressure is too high. Diagnostics start with test fuel pressure (engine off: 3.8 bar +/- 0.2 bar; engine idling: 3.3 bar +/- 0.2 bar). A vacuum leak on the line going to the fuel pressure regulator would also create problems, a vacuum gauge on that line should read 0.4-0.6 Bar.
  15. Every part in the HVAC system is available separately:
  16. You could have a bad lifter, which is not uncommon. The design of these lifters require very clean oil as they are a "dead end" design, meaning that there is a passage in, but no passage out for the oil. Dirt or debris can get trapped, causing the lifter to stick and make noise. A cleaner added to your oil may clear it, but that also tends to free up other debris in the engine and end up buggering other lifters. If it is a bad lifter(s), this is not really a DIY job as the cam covers have to come off, along with the cams, to access them. This requires special fixtures and knowledge of cam allocation procedures.
  17. That is pretty bad. You are going to need a new one, and as the dealer is needed to program it to accept your keys, you may as well just give them the entire job.
  18. Something is wrong here, the 174 fault has two possible causes, DTC P1531 or P1530, and the OBD II manual for your car does.not list a P1341 code, meaning that the DME cannot throw that code. Please reconfirm the DTC code.
  19. AGAIN, regardless of the date of manufacture, exactly which IMS design is in any given 2000 or 2001 M96 car can ONLY be determined by pulling it apart and looking. I have two M96 engined cars in my personal fleet, the 2000 is a very early production date, the 2001 a very late production date.. Both have been converted to IMS Solutions, but the 2000 is a single row engine, the 2001 is a dual row; exactly backwards from what the production dates would suggest. It is probable that many, but not all 2000 M96’s would be a dual row, but over the years of retrofits, I have seen enough that were not to realize that while the percentages favor the 2000 being a dual row, it is NOT a guaranteed outcome............
  20. Oil leaks and misfires are often the result of the oil getting to the coil packs and/or plugs. You need to get the car up in the air, find the leak and fix it. I would then pull at least cylinders 1 and 6 coil packs and plugs and have a good look at them. If the packs are cracked, you may be in the market for some new coils. Good luck.
  21. There is some leeway in that analysis; if the engine has the AT in the number, record the number as it will tell you what year it was assembled. If it was earlier than 2004, it would have the IMS bearing appropriate to the year, if the year was 2004 or later , it definitely has the non serviceable bearing.
  22. Your assumption that the 2000 is a single row is flawed, while this is some possibility it is a single row, experience says more 2000 were dual rows than singles. Again, the only way to know for sure is to look. You can also look for the engine number stamped into the pan rail, it is contains the letters “AT”, is is a replacement engine, and the rest of the numbers will tell you what year the engine was assembled, as well as what size engine it is. Probably the best advice I can give you is to find a car in the condition and with the options you want, and then have a competent shop do a pre purchase inspection (PPI). While this will cost some $, it should also tell you about if the engine assembly date coincides with the model year of the car, or if it has been replaced. It will also outline factors like how many times the engine has been run to the red line, and a myriad of other factors about how the car has been maintained and run. That data is a MAJOR factor in sale price negotiations, and can also prevent you from buying someone else’s problems. We once had an absolutely beautiful 996 in the shop that looked like it had lived in a plastic bag for the last several years; only problem with it was that it had a 2.7L Boxster engine in it instead of what should have been there, which explained the prospective buyer’s comment that is felt sluggish on acceleration when he test drove it. Used Porsche’s are definitely a “buyer beware “ proposition..............
  23. Welcome to RennTech Most 2000 and many 2001 M96 engines were dual row engines, which created the problem that the only way to know which style was used was to pull the transmission, clutch, and flywheel and haves a peek. There is no other proven method to tell you which version was used during the 2000-2001 transition period. If the engine was replaced with a factory unit, it would carry the letters “AT” on the engine number on the sump rail, and the number will reveal its year of assembly; all reman engines produced after 2004 carry the oversized non serviceable third design IMS.
