I have replace air regulator.
waiting for the delivery of idle adjusting screw unit (cuz I could hear air coming from it).
Replace AFM with remanufactured one but the problem have worsen, so I put back the old one and its better.
I will check further for cracks on vacuum hoses.
What is CHTS?
Thank you for your advice.
