Hi, everybody! I have a problem: My Roadster has a trigger/buckler/stutter when speeding up. They go up to about 3,000 – 3,500 rpm, and then it feels like it’s switching to another mode and then it’s back to normal. If it’s cold, then the problem is smaller – as soon as it’s at operating temperature, it gets worse. The whole problem started after I replaced the valve cover seal. And now the kicker: It’s not the ignition system! D he candles and cables are new (candle exchange has brought a short-term improvement – until it was again at temperature), and the coils are also fine. I didn’t have any clues for wrong air either. So I gave up and brought it to the workshop. There they found nothing – just one suspicion: the air mass meter. Do you think that’s realistic?
