Lower rad hose collapsing, probably. They're aftermarket, or old and mushy.

You're saying the temperature gauge *still* starts to read TOO COLD when you rev the motor, but shows normal when you let off the gas?

How long does the engine have to be over 3,000 rpm before the temp gauge starts to show cold? And how long *under* 3K before it starts to read normal?

The usual reason for collapsed hoses is a bad radiator cap - it doesn't let the coolant back in when the engine cools. Diagnosis of that part is easy enough; just look at the lower radiator hose when the engine is cool. Of course, collapse is still possible if the hose is no good. That is pretty obvious when you squeeze the hose when cool - it will be very soft.

Use an Acura TS. It's worth it,you will be certain you get the right temp TS,and it will be a fail-open,not a fail-closed type.
