What are your mods? The "top" spark plugs are the trailing plugs, the bottom ones should be 7's for easier starting in cold weather. Sorry I'm not much help troubleshooting, good luck to you.

There is no correlation between the plugs and injectors that I am aware of. In other words, both of your top (trailing) plugs are wet, but there is one prim and one sec inj per rotor housing and per pair of leading/trailing plugs. So, there is no easy way to tell which of your injectors may be leaking. Have you tried replacing your plugs? Also, are you sure that all 4 of them are firing?

firing meaning getting spark from the wires?

Yup.

i was thinking this may be it the plug wires have 120,000 miles on them

Well, then definitely replace them, stock NGK plug wires are fine. Just replace one at a time to ensure that you don't mix anything up.
