Idle issues when hot
Hello,
I have my '98 GS300 2JZGE. And it starts when cols fine and drive fine but issue starts when engine is hot.
Issue started just from nothing, stopped by traffic light and seems that 2 cylinders does not work fine. While driving it is ok. So.
Changed spark plugs, spark plug wires, ignition coils, cleaned oil control valve and it seems working, cleanetd ETCS, air flow sensor seems working.
My main concern is vacuum leaks or o2 sensors, because if I inplug any of it check engine does not appears on dashboard and RPMs does not change at all.
Any suggestions ideas? Thanks!

Did you look for any CEL codes? It should be the first step before you start throwing money on the car. You'll get more help if you give us the codes you get
I've got the same issues, and one of the codes that keeps reappearing is p1349 which is for VVTi system malfunction.
As stated many times before, even though the oil control valve seems to be working and has the proper resistance, it may not be working properly.
