Starts, Idles and Dies...
Hello 928 gurus! I have trouble with my 1985 928S again. Took it for a 100+ miles trip last Sunday, car performed flawlessly. My Idle is still a bit high though, 1100rpm...
Took the car out Tuesday, started right up, idled nicely. But as soon as I give gas, the engine dies. It doesn't sputter or hesitate, just dies like I turned the ignition off.
So one day everything is fine, the next it doesn't run. Nothing touched, nothing changed.
With my previous issues with over fueling on idle (most likely caused by the wrong type of coolant temp sensor), I have checked every sensor signal to the LH and EZF multi pin connectors. Basically every sensor on the engine is new (MAF, TBS, ICV, Air Temp Sensor, Coolant Temp Sensor, Injectors, Spark Plugs), and functionality have been tested. All vacuum and breather hoses are new.
What could cause this sudden issue?
THANKS!!!

did you readjust the MAF pot after installing the new MAF?
