  1. I had the same issue - 2000 996 110k miles was howling at the gas cap, idled high at times and wouldn't start after I filled the tank unless I held throttle wide open and cranked for 10 seconds. Started about 18 months ago year ago, but didn't throw a code until recently - then got these three: - P0446 Shutoff valve activated - P1128 Oxygen sensing adaptation (idle range bank 1) - P1130 Oxygen sensing adaptation (idle range bank 2) Blowing out the canister hoses didn't help - in fact I couldn't get air to pass thru those at all - they just pressurized. I recommend using
  2. Replaced the fuel pump. Went straight to the station and filled up with 15 gallons. Started up no problem. Think that fixed it. Thanks all.
  3. Thanks - I carry spare relays in the car but why would it only occur after refueling?
  4. I have a 2000 996 with 107k miles I had the AOS replaced about 20k miles ago. I replaced my crank position sensor about 5k miles ago to prevent hot start issues. For the third time in about 3 months (I don't drive every day) my 996 wouldn't fire after filling up with fuel. I had been having issues with gas station pump nozzles shutting off prematurely - in California where we have the vapor recovery nozzles that aren't good for topping off the fuel. But the only way I could get my tank close to full was to fill it very slowly. The first time I had the starting trouble after f
  5. Sadly this link is no longer valid. Does anyone have a chart for the relays in each position of both panels? I'm specifically looking for the fuel pump and DME relays. Many thanks
  6. I had the same problem (2000 w/ 90k miles) but cleaning the throttle plate resolved it for about 6 months. The plate was gummed up on the back side (could only see when pushed open). As noted above, when the plate finds its center point, the centering (clicking/vibrating) process stops. The centering difficulty and clicking re-appeared recently - I took the air box off and found both sides of the plate to be clean, though blasting the pivot pins with carb cleaner made it stop. Hopefully that is enough to solve the problem, though I may have to replace my body at some point too. Some back
