the symptoms.
engine rpm would not go over 1700 rpm if you keep the pedal pressed the engine will surge up and down, i had a snap on scaner hooked up and the absolute throttle readings was always zero i'am suspecting the throttle actuator,
or the n4/3 module.
is their any way to test the throttle actuator?

car has no asr.

I JUST tested the voltage at the throttle harness
and found no ref voltage at the plug , no 5v anywhere.
i puled the module n43 out and tested wire continuity
between the throttle plug and the module harness
everything is ok.
I 'm suspecting the module now.
