Greetings, I own a 944 1985/2 NA
Love it, but currently it's got me dumbfounded.
The issue is that the engine bogs down when i try to accelerate, but in waves.
It idles beautifully, but refuses to perform under load.
I've replaced:
Vacuum Lines
All air hoses
AFM (got a used one, so it's questionable)
Fuel Pressure Regulator
Fuel Pressure Damper
Injectors
Spark Plugs
Spark Wires/Coils
Speed Sensor
Reference Sensor
