Hello,

I have a GP SE from 1989. In the moment the car have a rough idle and consumes 3-4 litres of benzin more than usally. The temp. indicature lamp comes on when the temprature is rising to normal. The Temprature gauge shows a normal temperature. I have changed now both temperature sending units but there is no change of the symptom.
Spark plugs and wires are also changed at the same time.
Is there any body who knows what it could be?
Thanks from Germany
