If your car intermittently gets stuck in open loop you have a problem. If you haven't already done so, post a log of it happening. It's likely one of your sensors causing the issue. You mentioned when it does go in closed loop it runs bad, which also likely points a feedback sensor issue.

I feel bad for your situation, no offense. Nobody around to help, lots of problems, and many threads asking for help about countless problems. Somebody gives you good advice or helps solve a problem, then your onto the next issue without resolving any prior issues it seems. Not trying to be a dick, keep asking questions, but work on one thing at a time and stop daily driving your car if you are until it's all straightened out.
