Ok, we've got w reg saab 9 3 2.2 diesel turbo. recently (and not too long after a service with no major issues other than the sump plug ( ???) being threaded wrongly so alternative thingy had to be used), the car has started to 'pull'slightly when driving, this can be either during acceleration when going up early gears or when keeping foot on gas for steay driving (eg on motorway). the 'pulling' is more gentle, not major 'lurching' as such, but this aft, while pootling along the motorway the engine malfuction light also came on, and hasn't gone off! hubby checked under bonnet, no obvious probs. Any suggestions, anyone? Ta!!!
