Hello, I drive a 3, 2l V6 and have the problem that the engine in the cold area has ignition oscillators on the 1 and also on the 5 cylinder. After the oil has reached a temperature of 80 degrees, the engine runs smoothly and all cylinders work without any problem. Ausgelsen at the dealer also has only ignition oscillators Bank 1 and machsmal Bank 5 shown. All ignition rods & spark plugs were changed no improvement. Compression measurement was with all cylinders i.o. dealer meant I should possibly still make a pressure loss measurement, because he suspects that either a burnt valve or the pressure over the piston rings escapes. My guess is that it is an electrical problem. Maybe someone has an idea what could be the cause. For feedback I am very grateful.
