Hello, read here already for a time, but I have found nothing yet that could solve my problem. The following symtomatics. From about one week of service life: Keys hardly turned – runs like from the shop after turning off up to about 30 minutes: normal, if it becomes about 30 minutes, already a bit heavier jumping from half an hour to about one week: long organ, until it starts with an unround run, then finds itself after a short time and runs quite normal. rare: in the problem phase of 30 min. until a week — start without problems I’ve already taken the problem with my father-in-law for a while. Actually, he has always jumped at some point, but just annoying. Swap for new: ignition cable distributor cap incl. Runner temperature sensor to the control unit on the thermostat housing spark plugs Since I don’t have much on my hat with electrics, I don’t get any further without help. and on, although rarely, behaves quite normally when starting during the problem time. Compression I exclude, because he can hardly wait after a week of service life the key turning. I will still do this circuit with the starter, terminal 50. I will also install a new ignition starter switch. But I think that there is no problem. Maybe someone from the forum can help me. Look forward to any help. Greeting Robert
