There ar two thermo vacuum switches on the intake manifold,one in the center top by the EGR pipe right next to the valve cover,and one center bottom on the outside right below the carburator,it may be that one of them is not fully opening/closing when the motor is cold.I'm not sure on this as I've never had this problem with my 22R's,hopefully this will point you in the right direction,if you want comment back and I'll research this further(it's 5 in the morn and I cant access my 22r manual)

have you checked you fuel pressure regulator as some times as you rev the engine the fuel pressure will over fill the bowl or even simpler your fuel bowl shut valve may need re setting

wrong arrangement of piston rings affects intire performance of an engine. and must see that.
have you calibrate your injection pump? and change your injectors?
have a shop with scan-tool diagnose the problem.
