Suddenly Misfiring all over
2004 SL600 V12 twin turbo, 87K Miles, car is like new inside and out, I've put 2K miles on it in the last 15 months. Driving today, all perfect as usual, Suddenly check engine light came on and noticeable loss of power. I was a mile from home so drove gently and parked. Using generic code reader as I don't have an SDS... Codes: P0307, P0309, P0311, P0308, P0310, P0300. Looks like a lot of misfires have become the order of the day. Could it be that I need an ignition coil pack? That would be one side of the engine. Or maybe there is another cause? It can't be spark plugs or wires since this all came on so suddenly. Or possible fuel issue? Any help is always appreciated.
Please don't spill Champagne in the Mercedes.
