SOURCE: Rough idle until warm 22r
if it is a carburated engine it is probably the a.a.p. diaphragm in the carb. if you remove the air cleaner and look on the side of the carb that is towards the valve cover near the front yow will see a vacuum hose going to a cover that is fastened with 3 screws. if you pull the vacuum line off you will see that there is probably fuel being sucked into the line due to the leaking diaphragm. the vacuum source is temp controlled and cuts off when warm. but when cold sucks fuel directly into the intake. remove the 3 screws to replace the diaphragm, being carefull of the spring. good luck!

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)

There is an adjustment for the clutch pedal under the dash where the push rod goes thru the firewall. There is only aprx. 1/2" of adjustment so be careful when making an adjustment, if your clutch is slipping then you need to shorten the throw of the push rod.

First you have to bleed air from clutch fluid.
if it is not ok, Remove clutch agan & check pressure plate finger blance or damage.
