. NEED HELP WITH STALLING ISSUE DURING WARM-UP.

1994 Mazda Protege • 120 miles

My 1994 Mazda Protege with 120,000 miles stalls during warm-up. About 3 minutes after starting cold it will
stall several times. It runs OK once completely warm (after about 6 minutes of run time). Asking for
help to solve this issue.

I checked the fuel pump for correct pressure as well as the pressure regulator, both are OK.
The Idle air control valve is OK as well as the coolent temperature sensor and Mass air flow meter.
I replaced the throttle body gasket and added gumout fuel injector cleaner to the tank and replaced the spark plugs,
air filter and ignition wires. The EVAP solenoid purge valve is OK. Is it possible that a valve clearance adjustment
would solve?
I would appreciate any help!

Has nothing to do with valve lash clearance-check and test the EGR and PCV valves and also the TPS -sensor
