Because all your misfires are on 1 bank, I doubt it will be wires.
First go order a new MAF from Tony at the LRRF, 650-365-4145
install it then clear the codes again, drive it as little as possible between now and when it is fixed or you could kill you #1 cat.
By the way, the 1590 is a rough roud/ABS fault that will go away when you resolve the 3 Amigo's issue.

I just put my new MAF on order and it should be here in 2 days. Yay, I will get it put on and see what sticks after clearing. I paid 156.00 after taxes and shipping, so I think I got a good deal after looking on the net. Yes it's new, I won't go used for that. I appreciate the help and will continue to observe and put in my .02 now that I am back.
