Hello together My Viggen has been having power drop problems for several weeks after long colon driving (e.g. staggering at the speed 80 on the highway). This means that after a long period of time you never needed proper performance (about 30 minutes), the performance is no longer 100 percent after that. You have to stop then, ignition off and turn on again. After that everything is again io. Has someone already heard of such problems or even experienced it yourself? Many greetings Katja
