Default My rx8 won’t pass 3,500 rpms

I rebuild my engine and everything is good, the engine has good compression. But when the car warm up and I turned off and turned back on it won’t pass 3,500 rpms.
So I don’t know if the computer or something else
When I plug the air flow sensor the rpms goes up and down from 2,500 to 1,000 rpms but when I unplug it, it’s stays on 2,000 rpms like it normally would do.

Dirty SSV valve maybe or maybe the vacuum switch on it is going bad
