Dear Eric the Swiss,

Hope you're well. Does your car have a catalytic convertor? Cars sold in the U.S. had to be so equipped. I do not know what was/is required for cars sold in Europe.

I recall a long-ago post, where it was reported that the ceramic core of the converter had broken into pieces, so that exhaust gases could not flow properly. That "choked" the engine, limiting power output.

When the engine is idling (700-800 revolutions/minute, RPM), put your hand near the end of the tail pipe. There should be some pressure behind the exhaust. Then, have someone "rev" the engine up to 3,000 RPM, the value that corresponds to going 100 Km/H. If the exhaust stream is not much stronger, then a clogged catalytic converter may the problem or one of the problems.

Hope this helps.

Yours faithfully,

Spook
