Following a full service on the 996R I was looking forward to getting some miles under the new Corsas and went off on a jaunt with Webby to Worthing on one of the hottest days of the summer a couple of weeks ago. All went well until we got to the town and in the stop-start run through to the seafront the engine soon got up to 115C with both fans going furiously the enclosed fairing always run the engines hot in traffic. Coming back out of the town the engine started to lose power almost as if it was cutting out on one cylinder and it was a struggle to keep her going at traffic lights. Out onto the open road and although the temperature dropped the problem persisted you would get up 7000rpm and then the engine would slowly lose power until the revs dropped back down to 4-5000 open the throttle made it worse, then all of a sudden full power would cut in and wheeeeeh
After a while the problem disappeared and didnt come back until the engine got hot again some days later. Over the last week the problem has been there almost constantly so I spoke to Snells who managed to free up Carl for a couple of hours to look at it. Prior to going I armed myself with a new ECU just in case courtesy of the kind and generous Andy Banes (andyb) who sent me three to try thanks Andy
Well, the problem is now solved. Any idea what it was? A prize for nearest the right answer .....
