Already put marvel mystery oil when I changed the oil, I haven't checked the cap and rotor but I will when I do the manifold. But when I put the spark tester on the plug for cylinder 1 which is one of the ones that's misfiring it seemed to be sparking fairly regularly. Also of note is that bank 1 is running normally or slightly lean around 5% and bank 2 is running rich at around -10%.Have you checked the basics? Cap, rotor, wires. Kinda would explain that the skipping goes away as it revs up. Also clean MAF due to it sitting. Can't hurt to throw some Marvel mystery oil in the oil.
I will check the wire routing out. Currently I'm just waiting on the spider to arrive to do the manifold. I think I'll be doing it this coming weekend.after replacing my plugs, wires, cap & rotor, my rough idle didn't go away. it was suggested that my wires weren't laced correctly. 2 of my wires didn't match the diagram, so I relaced those 2 & no more rough idle. while it didn't solve my misfire, it sure does run smoother.
