Just thought I'd stick a post in so I can hopefully help people If they had same problem I did. I work in a garage and got a disco in last week, sluggish, hard to start, cutting out after a couple mile, so straight away looked at plug at ecu, soaking with oil, new injector harness in and oil cleaned up, still no better, so looked into it abit more and ordered up injector seals, copper washers and o rings, stuck thm in, result, no cutting out, going far better but still not the best, only taking off when the turbo kicked in, so air flow meter on and customers says its never run better, so if ure discos cutting out good chance good be injector seals
