Cleaned the MAF? And verified that it's functioning properly (maybe try one from another car)?

That picture is clearly the headlight fluid reservoir.

IMRC actuator is failing.

Its the control unit that sits under the intake that controls the butterfly valves that open up the 2nd intake valve on each cylinder at 3250rpm. I'd almost put money on it. Mine went bad on my 96 and the dyno looked like an EKG all the way up to 6k, and it took almost 30sec to get it there. Mine didnt idle weird though that i can remember

I was thinking that would could be a problem as well. I would just delete it and the butterflies and call it a day

Good catch, Scott.

I completely forgot about IMRCs.

Blue injectors are 24#'s, and that pic almost looks like an intercooler pump.

If he has replace all that, then its either the ecu or blown head gasket.

Check the voltage at the TPS and make sure it's around .95-.98 volts.
