If you have already pulled codes up, then I would fix whatever is causing the codes before I spent the money on a new computer.

Also, the A/C compressor code may cause some weird idle problems. When the compressor is running, it is loading the engine. At idle, the computer will make adjustments to keep the engine idling high enough since their is a load on the engine caused by the compressor. It may or may not be causing the exact problem you are speaking about, but I would get those codes cleared and fixed before I bought a new computer.
