fire order please help

I got a 1997 F-150 4.2 no 4x4

I think i got the correct order but the truck is not running on all cylinders. Could it be because of cheap spark plug wires? Some of the old ones broke in half so I can put those back on....

I bought crap spark plug wires from Autozone. I mixed up the firing order so I don't know where they go. I saw a similar post on this forum saying it goes.


Is this correct

Welcome to the site!

Your firing order is stamped on the intake manifold.

Probably not. I believe that your layout in the first post is correct.
