My purge and evap solenoids tick along with the injector solenoids, but the injector sometimes the ticking is real loud, usually just moderate but also goes away for a while.

Not sure at all whats causing this, all I run is 93 + octane and changed the fuel filter.

I noticed their is a rectangle block of wires think 4 wires come out of this and its mounted on the firewall, then runs into a relay / solenoid and from their up into the purge solenoid.

Could this be the problem? If so what part is it?

I tried looking through the entire emissions diagram couldn't find it.

EDIT:

My downstream O2 sensor is shot which is what is causing all my problems.
