DME Tempurature Switch
1987 944 NA: Because I'm still chasing a stumbling acceleration problem, I'm looking at the DME Temp Switch. I did all the fuel system pressure and leak down tests and everything was spot on.
The Clarks manual says the switch readings should be 280 ohms at 15 degrees C and 360 ohms at 80 degrees C. Mine was 95 ohms and 250 ohms respectively. Have I finally stumbled upon what's making my DME cause the engine to stumble at wide open throttle? The engine runs great otherwise.
I've replaced the injectors with rebuilt ones, fixed all the vacuum leaks, new ignition system, fuel filter and good fuel. Rebuilt the AFM, removed the mouse nest from the airbox
and all new belts and seals up front. It's a process.
