I managed to get the intake off this am. Had to disconnect the Air Suction pipe. Although the HELM showed both the Air Suction and the EGR pipes being disconnected, only the Air Suction pipe actually had to be disconnected.
When I planned this Water By-Pass repair I decided to change the heater hoses as well as the control unit. With the manifold off, it was relatively simple. I also used OEM spring clamps because of the difficulty in trying to get a socket or screwdriver at a clamp, especially the LT side hose. I also changed the O-ring on the water passage pipe which connects to the rear of the thermostat base. Now was the time to do it.
When you repaired the head-gasket did you replace the two Fast Idle Valve hoses? If so, any suggestions? I could not get at the OEM spring clamps and ended up cutting the hoses in order to remove the Fast Idle Valve. On reinstall, I very carefully positioned the new hoses to the the old, and then using OEM spring clamps, clamped the hoses both to the nipples under the intake manifold and the valve itself. I hope I have enough hose lengths and correct angle to allow me to just push the valve back and then reinstall. I don't know how Acura does it unless they access those clamps from under the vehicle while the vehicle is on a lift. I may have to R&I the intake several times in order to adjust hose length an angle in order to remount the Fast Idle Valve to the manifold...unless you replaced them and can offer suggestions. I have even backed each hose off about 1/8 inch from the stop of each nipple to give me a little "wiggle" room.
Have added Fuel Injector cushions, seals and O-rings to the repair list. Two of mine were seeping. This repair is like "The House That Jack Built".
Thanks for the information and response.
Did a "dry" fit of the manifold. The Fast Idle Valve fitted perfectly. DIY write-up tomorrow.
