The 33, 35, 37 codes are indicating there is a short associated with the AC, which is affecting everything else from the looks of it (it is tied in with the idle control circuit/speed).
the 13 is the idle circuit/vacuum line problem.
They all seem to be related problem and sound like it is the place to look first, so a slight wiring short somewhere prpobably, or dirty connection. Here is the codes, and if you read them, they will make sense.
