  1. I think your car is a 993 (not a 996) and I think the problem you describe is fairly common on 993's. Here is a copy of post from the PCA website where a person fixed this problem without spending a lot of money.

    cleaning secondary air injection ports -- SUCCESS!

    I just finished cleaning out the air injection ports. It was a lot easier than I expected. I did deviate from your procedure in one respect, which I think made it easier. I replaced the check valve between the air pump and the camshaft housing. Instead of pulling off the solid pipes that supply the camshaft housings, I poured Techron in the hole that the check valve came out of. Doing it this way, I didn't have to mess with the power steering pump or any of the plastic parts on the left side of the engine.

    The only issue was that I had to plug all six ports at once. To do this, I cleaned the exhaust port with a carb cleaner and a small wire brush on the end of a drill and then plugged the holes with used chewing gum. It wasn't perfect, but it worked well enough to get the job done. After running the Techron through, I sprayed carb cleaner both from the top and from the bottom using the little red plastic tube that comes with the carb cleaner. It was flexible enough that I was able to stick into each port and spray the carb cleaner up into the passage way. I then blew compressed air through from the top and let everything dry out.

    All of the air ports were open, though the #3 exhaust port itself had more carbon build up than the others. Is this common?

    The whole job took about 6 hours, which included about an hour of trial and error modifications to a 15/16ths inch wrench with a bench grinder and a torch to fabricate a tool to remove the check valve. One reason it was fairly easy is that I have a lift in my garage. I imagine it would have taken longer with jack stands. Now that I have the tool to remove the check valve and know what I'm doing, I figure I could do this again in about 4 hours.

    How often do you suggest to clean the ports as preventative maintenance? Feel free to post this on the PCA website if you wish. I read that some people in Sacramento were going to clean their ports, and I'm wondering how their efforts turned out. Thanks for all your help. It gives me a certain peace of mind knowing that I could see that the ports are completely clear and that the dreaded check engine light isn't going to come on at any time---not because of clogged secondary air injection ports anyway. Take care, Rob.

  2. 996 731 619 30 Left Door Mirror (Carbon)

    996 731 620 30 Right Door Mirror (Carbon)

    There does not appear to be any special "RS" mounting hardware in the parts list.

    Loren, do you know how much porsche charges for the mirrors? I'd imagine its quite a bit since their markup on CF is rediculous.

    The "retail" prices I have (as of Dec 2004) are:

    996 731 619 30 Left Door Mirror (Carbon) $966.24

    996 731 620 30 Right Door Mirror (Carbon) $966.24

    It pays to shop around - try Sunset Imports (link at top of the page). They sell at dealer cost plus 15% handling and shipping cost -- AND -- no sales tax.

  3. These bolts are microencapsulated. That is, the bolts have a special sealer on the threads and once they are tightened the sealer activates and seals for leaks. If the bolts are removed then the sealer is destroyed and they must be replaced. Just get the torque setting right (see the TSB because they are different depending on location) and they should be fine.

    Availability is likely a result of how many RMS replacements they are doing :lol:

  4. The O2 sensors are just that - sensors. They are likely not the problem but the problem reporting mechanism.

    P1123 Oxygen Sensing Adaptation Area 1 (Cylinders 1 - 3) - Lean Threshold

    P1125 Oxygen Sensing Adaptation Area 1 (Cylinders 4 - 6) - Lean Threshold

    This would mean that the fuel/air mixture is so rich that sensing is up to it's lean threshold and can not lean the mixture enough.

    My list of probable causes are: fuel pressure too high; fuels injector(s) leaking; EVAP canister purge valve open.

    Could be the charcoal canister (which should be covered under emissions warranty) or fuel pressure too high because of dirt stuck in one of the valves or a bad fuel pressure regulator vacuum connection. In the end all of these may be covered by your emissions warranty (unless it was caused by a dirty fuel filter/fuel).

  5. If you haven't lately... replace the plugs, wires, cap, rotor. Change the fuel filter and check the fuel pressure. Adjust the valves. Check for intake or vacuum air leaks.

    Unfortunately any of these could cause your problems - so you just need to eliminate them one at a time.

  6. Remember there were two GT3 styles from the factory. The pre MY2002 GT3 (for RoW) and US Aerokit Cup and the MY04 GT3 that has the new style fenders and headlights. The bumpers are not interchangeable since the fenders and headlights are different.

    So if your car is a MY02 or newer you would want the MY04 GT3 style (or Aerokit II style) front bumper.

    I personally wouldn't worry about being a poser -- the fact is the GT3 style bumpers have larger openings for air to the radiators. I can't think of a good reason not to have that.

    I believe all of Gert's (Carnewal.com) bumpers are factory parts unless you specifically ask him to get another brand.

    BTW... RennTech.org does not have advertising sponsors per se. What the featured vendors here do (to be a featured vendor) is give RennTech.org members a discount - RennTech.org receives no advertising monies from any vendor.

  7. Pull the A-pillar trim inwards along the roof frame and windscreen frame. The A-pillar trim as of MY2000 is characterized by a changed curvature and the notch for the deformation element.

    Before installation, check that the deformation element is seated properly. Check sheetmetal clips and replace if necessary. Insert the A-pillar trim at the side of the windscreen frame (transition point to dashboard), clip in the A-pillar trim along the roof frame.
