Can you help me? I need the diagram for plug wire locations on the distributor cap.

Also, if you have the timing diagram, I pulled the timing cover, I found the makings on the head, oil pump case and the cam gear. I did not find the mark on the crank gear to match it with the mark on the oil pump housing. Thank you for your help.

Hello,

Those misfire codes can be due to a number of components.

I have attached the firing order as well as the timing marks below.

Let me know what you find or if you have any questions.
Thank you.
