Sounds like it could be the airflow meter between the filter box and the inlet manifold.

Dealers in the UK will hook a car up to the workshop computer for around $60, which will give all the fault codes. But fixing stuff cost much more!

My Skoda (20 valve 1.8 litre turbo)had a misfire which took 3 days, 2 computers and 2 mechanics to cure, caused by a signal amplifier between the ECU and the (Individual) coils.

Give me a simple V8 on carbs anytime!
