Firing order and cylinder #1 location
Does anyone know if the m177 firing order is 1234 5678
Facing the front of the car banks 1234 would be on the left and 5678 would be on my right side ?
I have a cylinder 1 misfire after changing my spark plugs. CODE P030185
I just changed spark plugs, set them to give gap . They are oem factor plugs, already pre gapped. Checked gap just in case, also torqued the ignition coils to spec.

Cyl 1 is passenger side front of engine.
swap plugs from cyl 1 and 2 to see if misfire follows to cyl2. If it does, plug may be bad.
if it stays in cyl 1, swap ignition coils from another cylinder and see if misfire follows the coil. If so, faulty coil.
If neither could be faulty injector. Or could be bad gas.
