Erratic idling when off aircon while stationary

[sorrow]

Hi all, need help

I got prob with my car, my idling becomes irratic after i switch off my aircon when i'm stationary and dies out after that, so any bros experience this before? This problem came onli after I replaced my faulty igniter (inside distributor assembly)

Scenario (Mine auto btw)
1) Moving and switch off aircon, no problem
2) Moving and switch on aircon, no problem
3) In Drive mode, stationary, switch off aircon, idling goes erratic and engine dies out after
4) In Neutral mode, stationary, switch off aircon, idling goes erratic but stabilises after that

Have checked aircon with aircon mech, no problem
Have checked with another mech, he say my fuel injector dirty, i just send it for cleaning so most prob not it.

Mine is a 1993 XLI corolla...hope bros can help, many thanks in advance
