my slot in question again. my wira 93T.
have all the symptom stated above at early part after swapping engine.
Some troubleshooting i do it myself. ISC replaced. TPS adjust according to online manuals (resistance continuity reading).
BISS screw adjustment made. Before change ISC, BISS near full open. Now fews round from close position.
Cold start 1500rpm slowly drop to 700-750rpm.
ON air-con rpm jump to 950rpm. Drop to 550rpm when compressor kick in, then up to 900rpm. ISC is working.

After drive for 1-2 hrs, normal one. OFF engine.

When start back the engine after 1/2hr (warm start), rpm stay low. 550-600rpm. vibrate.
ON air-con, all back to normal. OFF air-con, car idle normal.

I got read from pomen_gtr about oil filler cap leaking. Cause irregular idle.

Pls help me to continue further my diagnostic. Thanks sifu.
