What Cylinder is what ? how to count ? Ml320
 

I have a stumble at idle.
Bought some low mileage coils and wires.

Replaced both banks centers , was not getting any codes.
Now I do. PO305.

I am guessing. I thought it was left bank front to rear 1,2,3
right 4,5,6. ran an engine search and came up with nothing.

Update..I am an imbosole, I neglected to snap in the coil wire on the middle drivers side coil. That has to be the #5.

Passenger side of engine starting in the front is 1,2, & 3.

Drivers side is 4, 5, & 6.

Number 5 is the middle cylinder on drivers side.

THANK you very much
 

Confirmation is good.

I should have said drivers and passanger instead of left and right.

I just think about tires...is a right tire ever on the drivers side in the USA ?
