I have a Xantia 1.8 8v from 1995. My problem is that my engine doesn┤t run
smoothly under normal acc. And when yo let go of the gas pedal, it doesn┤t
do it as smoothly as it should. I hope you understand what i mean, i am from
Denmark, so english isnĘt my best language. :-)
The car has 270K km on the clock. The engine is in good condition, and
doesnĘt use "any" oil. I have been told that it could be the Thottle
Potentiometer or Idle Speed Stepper Motor, what do you think?
It runs OK at idle.
I have changed oil, oil filter, spark plugs and air filter, so that isn`t
the problem. Have also changed petrol filter and pump.
I hope you can help me.
