Hello Elkfriends Since the very latest, my elk has been jerking like crazy. The car can be started perfectly but as soon as I want to go it jerks and makes the impression as if the engine runs partly only on four cylinders. What I have already controlled or changed – ignition cable – distributor fingers – ignition distributor cap – ignition coil – spark plugs (Original Volvo, looked good, i.e. neither damp nor burnt off – have changed them anyway, no effect) – injection nozzles – fuel Relais – Gasoline pump error is not saved, slowly I run out of money and imagination. Due to the symptoms I (with the help of the free opinion of the mechanic around the corner) simply excluded that it could be the throttle valve or a defective cat. What I could make out here in the forum as a possible error source is the camshaft sensor and the fuel filter. Can it be that a dirty petrol filter can have such effects? Does anyone still have Another tip for me?
