On 2nd take all problems pointed to fuel starvation which could be caused by a vacuum leak (hence the engine would cut off fuel). The car became difficult to accelerate but reasonably happy to run with a few misfires at a steady load. However, it was the Direct Ignition cassette that was faulty. On 2nd visit to the dealer they chanced that this was the problem. I had done 380 miles with the misfire. The catalyst apparently survived. I am happy to settle for half the SAAB Experience.
