Hi. I have my first problem with my Ommi. In idle or park or neutral position the engine runs smoothly and when giving gas everything is normal. But when I go to D , it starts to run uneasy as if it only runs on 5 pads. When giving gas it does not take the gas so well and only runs when I make fire, right again. Is this a possible indication on the spark plugs? Can unfortunately not find out clearly when they were changed. Greeting Nobby
