My idle has failed me. Car starts and drives fine, full power but wont idle unless you feather. This happended last night driving home from work. Car will idle for 15-20 seconds then die. Ran codes and got 11 (crank angle sensor) 12 (air flow meter) 13 (chts) 23 (idle swicth circuit) 24,31. Disconnected and got the same codes again. Where do I start?

I have a mbc set on ten. It holds boost steady at ten so no leaks, it was raining the other day so I tried to turn my boost down a few clicks. Nothing happened, it would not turn up or down but I still had 10 on my after market boost gauge. Thought the ball and spring might be bad so I ordered a new mbc. Put it on and still it is stuck at ten. It boost just fine and holds but I would like to turn it down sometimes. What do I need to be looking at to gain controll of my boost?
