Couldn't nail this answer down with a search. I just bought a used '03 CLS 6 speed and I'm Looking for the cylinder count for this V6 Engine. I'm experiencing a misfire on 1, 4, and 6 and this is after I've put in the proper plugs for this engine-had Bosch, swapped to the proper NGK's. I've swapped coils but the same cylinders are misfiring so from what I've read could be bent valves on those cylinders Car has an extended warranty from the dealer I bought it from so I can get it fixed under warranty but I always like to diagnose the problem before I take it in. So the question is what number cylinders are close to the front of the engine compartment, and what numbers are close to the passenger cabin. if you could also detail starting from Driver Side to Passenger side while standing in front of the car that would help...thanks...
