Follow fanaudical's advice to baseline, then change one thing at a time.
That said, I don't think those injectors will clean up, so buy new ones. Our host's price is competitive with the cheap Amazon sites, and you can get new sleeves and O-rings with the injectors for a great package price.
Although Alan and I thought that the most likely cause for poor idle, but better running with more throttle, would be vacuum leaks, poor injector spray patterns cause similar symptoms. As the fuel flow increases, the spray pattern usually gets better, and the increased air flow better mixes the fuel, so it runs smoother.
You can replace the injectors before running the CIS pressures test because the injectors don't affect the SP or CCP or WCP. However, procedurally, it would be better to measure those first.
If you plan to just drive it for the summer, replace the injectors. You need to do that anyway, and that might solve most or all of your problem.
