I got the car to start....
The 928 will start up two different ways..
1) Running a hose down the AFM keeps the flap open and car starts (The Temp II is connected)
2) With the hose removed from the AFM, the car starts but with the Temp II Sensor disconnected...
We know it only fires up when the Cap to the Temp II Sesnor is removed...
We know the cap to the sensor is severly cracked...
We know a resistor was added to compenstate for other related issues...
We know the car was running fine without any issues before...
What will I do tomorrow...
I will replace the sensor and cap....should arrive tomorrow at noon but I have to work so I wont get to it until after
