No, she said it started fine and she did not even realize anything was wrong until she drove away. 3000 miles later, all is still fine. And, there is a small horn noise when I lock the car. Never did that since I've owned it either.
Okay, Time for an update. Sent my DME unit as well as the security(?) box (under the seat) off to Specialized ECU Repair. ECUdoctors.com. Excellent group of people. They checked my system and told me that they could not get it to replicate the condition on their system. I rec'd everything back yesterday afternoon, reinstalled the boxes, turned on the key, performed the throttle adaptation, and problem gone. The only thing that I can think of is that there may have been a loose or bad connection on the box under the seat. And looking back, the problem started when my girlfriend was taking it to the store. So maybe when she adjusted the seat up, a connector was just loose enough to cause an issue? I wish I had a definitive answer, I do not like intermittent problems. But for now my trips to project meetings will be a lot more enjoyable. Thank you everyone for your input!
Did you find the cure? I did everything you did, and more. Luckily, or unluckily our winters are long, so I messed around with it all winter. Checking all the wiring, controls, etc.. Finally sent the DME unit to be checked. Will know the results in a few days. I was just wondering what the fix is. No one I have seen on the inet has ever posted a resolution. I doubt there are thousands of these cars in garages not running. I do not have the luxury of being near a dealer or a qualified tech. Been working on my own pcars for over 12 years, but this one has me stumped.
Maybe someone could answer this. I may not be 100% accurate. During the start up process, the DME unit sends a quick test signal to test the spring return. Does the DME check the throttle body itself or does it check the unit under the dash that sends the signal to the TB?
As soon as the paint in the garage drys I'll get back to the car. Probably will clean and re-install the old, then do the adaptation and see where that goes. I am 5 hrs away from a P car dealer, and would rather repair it myself if possible. I'm actually closer to Quebec, Canada. Only 3 hrs from there. Weird part about all this is this issue is all over the internet, yet no one ever has posted what the final resolution to this issue was.
Yes I reset the fault code and everything runs fine until you shut it off and restart the vehicle then it is right back to the issue. I do have the old TB. Maybe I'll try cleaning it real good and re-installing it. I've tried everything else. Someone on another site told me the DME should be reflashed to accept the new TB.?. Anyone try that?
I've done everything including that, wire inspections, cleaning the new tb, looked for vac leaks, etc.... No other codes, just that. Read about this same issue all over the internet, but no-one ever seems to show what the final fix was. There has to be an answer, or there are a lot of these cars sitting in garages. Should have never got rid of my 911!
Have had an issue for a while on a 2000 boxster. Runs great if you re-set the fault codes using the Durametrics software. Then upon a re-start, no throttle above 1500 rpm's. Replaced the MAF sensor as well as the throttle body. Read that there have been many with the same issues, but no one ever seems to post the whatever the eventual solution was. Has anyone had this experience and was it a reprograming of the dme unit? Was it something else? Searched for broken wires, bad grounds, disconnected everything for a period of time, did the 1 minute on, then off, then start, nothing.
