  1. Thanks R! I thought they moved things around between 02 and 03. I just got an updated Durametric software and it has a feature called something like Build Mode. I believe it is a way to force actuators to a given state. I'm going to see if this could advance / retard the cam. It would beat laying on the floor, fiddling under a hot engine. I am surprised that your bet is on the actuator rather than the sensor. The code seemed to indicate a no signal condition. I was kind of hoping for a bum sensor rather than a stuck actuator. Last one had to be taken apart and the debris screen (which provi
  2. At the time engine ran away, you were on the clutch and brake, but not the throttle, right? That makes sense if you were preparing to shift rev to fwd. New pedals? Possible your foot caught the throttle while pressing the brake? Remember those runaway Audi 4000's? Possible that the pedal installation is such that the brake pedal itself can catch on the throttle? Not even directly, but say the pedal snags a wire and the wire presses the throttle. I'd look carefully at this installation. I hate when the engine spins 5800 RPMs more than I tell it to.
  3. "Unsafe handling" is of course subjective. If you drive slow, it's not unsafe. If you drive a little fast, it's a little unsafe. If you drive way too fast, it's way too unsafe. The unsafeness I think shows itself mostly in the way of unpredictability. Wet road, oil slick surface on a turn, off camber washboard. You apparently have loosened the car by using a tire with a softer sidewall. I know this one firsthand by mounting Toyo R1A's on the rear of my 996. Car that used to handle like a gocart, changed into a Lincoln. After the tread wore a bit (very narrow, deep, flexible tread profile) the
  4. 2002 C4 Cabrio. Threw code P0349 "Camshaft position sensor 2 Open circuit" and check engine light. CEL went out after 2 days, and the varicam works sometimes. OK, seems likely that there is an intermittent wire or sensor issue but..... I took data with Durametric. Both banks, cam specified and actual angles, also RPM to see where the actuators moved the cam. I have included the XL graph. It confuses me. It shows both banks doing the same thing, apparently correctly. At the time I shot this data snap, the varicam was definitely not working (It's easy to feel). Any thoughts? Also other quest
  5. Such a stubborn, condescending view begs for other opinions. Here's my 2 cents. It doesn't take a "self proclaimed expert" to know that there is fuel in the tank without using a dipstick. The expert can monitor the fuel level gauge and if there is no reason to disbelieve the gauge, he can tell the level from it. Much in the same way, a "self proclaimed expert" can monitor the "combustion profiles" (boy there's a twenty dollar phrase) by monitoring knock sensors and ignition timing "profiles". The knock sensor feedback is quite simply a monitor of "There is detonation" or "There is no detona
  6. 02 C4 Cabriolet. The car is always in my garage or in the building at work so it has never gotten cold. Now I have to park outside sometimes and when leaving work (maybe 32F), I get a severe creak only at near full lock turn. It sounds like either a posi unit that sticks / releases or a tire that is being dragged because of too tight a posi. Any thoughts?
  7. Mike at Bodymotion says changing the bushings is more dramatic than changing a swaybar. And this makes sense to me. I recently put a bigger TT rear bar in my 02 C4 Cabrio. I had to also get bushings to fit it. The new bushings were surprisingly soft. I can see how a lot of motion could get transfered through the bushings before the bar even starts working. Multiply this compliance times the number of soft bushings in the car and I'll bet it's significant.
  8. "Three way converter." Catalytic converter in English. Took me a while to find that one as service manual and PET both call it catalytic converter.
  9. New separator is as good of shape as the day I got it. It has been sitting in my storage room at work since then. I haven't seen any smoke in many months and my oil consumption has actually decreased from 1 qt / wk to 1 qt / month. I think the prev owner didn't drive or break in hard enough to seat the rings. That's the only type of oil consumption I can think of that could get better in time. So..... I'm not looking for an unnecessary project right now and the separator will remain in inventory til something changes.
  10. I mounted Toyo T1R's on my 2002 C4 Cabrio because I loved them on my Vette. Now I have a Porsche that used to handle like a gocart but now it's more like an old Lincoln. Never again.
  11. Huh? ABS and PSM related to emissions? Silly me thought they stood for "Antilock brake system" and "Porsche stability management". I guess a fiery crash would affect the overall emissions of the vehicle.
  12. Wheels don't just fall of Porsches (or anything else). There are no special techniques that are needed to prevent it other than don't go back to the same dealer. And the "lot of people who know cars" are idiots. You don't have to Loctite anything. You have to put it together correctly. That's all. Make a list of these "lot of people" and next time they give you automotive advice, ask someone else. Anyone else. Anyone.
  13. I vote for the Sears thing. If...... it doesn't scratch the wheel.
  14. Essex New Jersey, Essex England, or one of the other 5,000 Essex's around the world?
