Re: [DMCForum] Rumbly rough running

["Martin Gutkowski" <webmaster@xxxxxxxxxxxxxx>]

This car has a Volvo metering head and therefore no lambda system. Any 
kind of metering anomoly, one should be able to trim out with the 
adjsutment screw at idle (even if it doesn't run properly on revs).

Could be the ignition ECU - that's a good point....
