After you have ruled out the basic tune up items, you might end up with the Air Mass Meter being the problem. Typical symptoms are wide idle swings and stalling when cold in the morning, followed by surging and flat spots when warm. The only practical way to test is to swap in a known good one.
Plugs should be NGK bcp7es or 7ev. Gap should be .024".
OEM rotor is important. Resistance should be 1k ohms betwen tip and center contact.
Your wires appear to be OK.
Sometimes the temp sensor(under intake runners) for the ECU can cause problems, but usually running issues when engine is warmed up.
Make sure throttle position switch clicks just off idle.
Make sure vacuum hose to fuel pressure regulator holds vacuum and doesn't smell like gas of have gas dripping out of it.
