Glad to hear it's improving. But I think you've still got a lot of work ahead of you. Definitely some treatment is in order to clean the engine beyond the fuel injection. To clean the injection, i'd recommend removing all of the injectors and having them ultrasonically cleaned and tested. New fuel filter, possibly a pump and complete flushing of the fuel tank and lines is in order. Oil sitting in the fuel that long can promote much worse varnishing vs. old, clean gas sitting for a long time.

I agree. Flush out the fuel system with clean fuel. I'd even jumper the dme socket to make sure the fuel pump is working correctly. Then remove the intake system and clean the intake manifold, throttle body, afm, the ICV, and send the injectors to a cleaning service. Drain the old oil, and re-fill to the correct level. The ICV probably does not even work correctly. The air bypass screw in the AFM is probably all clogged up as well. This is way beyond Seafoam.
Otherwise, you are just running the engine and forcing it to ingest all that gunk. I would quit running it like it is.
