I'm sort of wondering what made you rule out the idle air control valve so quickly?

yea, you souldnt clean the maf with anything you could mess it up more, anyways, change ur pcv its like 5 buxs, are you running a stock intake box set up? ohh yea, didnt u rebuild this engine recently?

I didn't have any problems when it was cold either. Someone correct me if I'm wrong, but I'm going to guess the IACV regulation is only active when the engine is at normal operating conditions.

i think you should open her up and reset timing.

High idle, misfiring...did you ever bother looking for a vacuum leak? When it starts chugging, spray some carb clean around the area of the intake manifold/hoses, ect. If the idle calms down or changes, you have a vacuum leak. Use more direct sprays to narrow down the area of the leak and fix it.

i have the same problem. when my dohc starts bogging/hesitating the temp gauage shows that the motor's getting cooler.

I had a bogging issue as well on my DE-T b4 and practically did the same thing as you but mine turned out to be a loose connection on the ECU. Had to zip tie the connector on both edges to make a good contact not just rely on 1 bolt. Something I learned >** Never tigthen the ECU connector too much it will bend **. Fo you I would check ground or any possible loose connections specially to the sensors.
