Let's start with the engine issue. Checked your spark plugs recently? Checked the spark plug gap? High pressure (boost) makes it harder for the spark to jump. If the gap is too big, you'll get no spark under high boost conditions, and that'll cause the engine to stumble. Spark plug gap tends to increase as the plugs age. Check the gap on the plugs, and make sure they're set per the manual. Make sure they're NGK's. I believe your engine comes with the DI cassette, and that is VERY particular about spark plug type. If the plugs check out, it could be an early sign of a bad DI, not being able to make spark. Pull the DI and flip it over. Remove the plastic cover (held on with screws) and flip it back over. See if any of the coils (white plastic things) are showing signs of leaking. Hold it up to a light and see if the level on one or more is down. If the DI is leaking, that's a sign that it needs replacement. If you have a distributor, it's probably time to replace the spark plug wires.

ACC issue. It might be the ACC head, but it might be two separate issues. I assume the fan is on high, no matter what buttons you hit. If so, most likely the driver transistor for the fan is shot. This is replaceable. Again, see Quasi's site at http://www.quasimotors.com/transistor.htm
As to being stuck on Hot all the time - the heater core is always getting hot coolant. A mixing flap mixes cool outside air (or air conditioned air) with air from over the heater core. If that flap is stuck in the HOT position, you'll always get hot air from the core. The flap is mounted below the blower motor and above the heater core. It's actuated by a servo behind the dash. Again, Quasi to the rescue-

In the example he shows, the arm has broken. It's also possible that the wire has slipped off. If the flap is floating free, hard maneuvers can cause it to move to new positions.
