Misfire code p0302 cylinder - 2004 Mercedes-Benz Mercedes Benz Slk Class

Fuel injector may be restricted or hung open .

P0300 multiple misfire
P0302 misfire cylinder 2
P0306 misfire cylinder 6

miss fire check coils or plugs

P0300 = Random/multiple cylinder(s) - misfire detected.
P0302 = Cylinder 2 - misfire detected.
P0304 = Cylinder 4 - misfire detected.
P0306 = Cylinder 6 - misfire detected.

A misfire can be caused by a few things. The most common causes are usually spark supply or fuel supply. Get BOTH of these checked.
All the misfires are on the same side of the engine so I would suspect a fuel rail or an injector issue on that side of the engine.

Remember to put the o-ring on the new one or this problem will happen.
