thanks guys for ur suggestions, I really appreciated.
I'll try that tomorrow when I get the Brake Cleaner.
Where is the PCV located and where should I apply the Brake Cleaner exactly?

Could you please tell me which part# on the diagrams I've attached below
I also got error #115
HOT-FILM MASS AIR SENSOR
I've cleaned the MAF Sensor with "CRC Mass Air Flow Sensor Cleaner" and derived the car 55 miles now, CEL did not popped up yet.
I'm not sure that the error #115 came before i cleaned the MAF or after.
I just cleaned the ICV as well, it was really dirty inside.
many thanks
