Hello, just ask me which ignition coils I should install? To the problem: My engine runs when it is cold very bad and starts badly, moreover it is extremely fat current consumption from 30-50 liters to 100km. My ignition coils are full of oil, so also the cylinder head. Is this perhaps the cylinder head seal? Well, I think that the ignition coils cause the engine problems. I already ordered new spark plugs, ignition coils original are Bosch, which are at knap p 35-40 Euro however too expensive. Does anyone have experience with the topic or tips which one can/should build? MfG Dome.
