Hello Since today I have the problem that my car takes heavy or delayed gas….. If he then assumes it reacts so treacherously. If he is on the road then he does what he should, just keep gas away and get back on the road quickly is rather bad. If I hold the gas constantly about 3000 revolutions I have the feeling that at irregular intervals someone is holding and letting go again. At the same time the speed varies and it is a strange light grinding Wär e nice if someone knows each other. Vg Lutzek
