Thanks for the valuable info shared as per below.
I m getting a little bit confused now. From the points of you, what should be the correct steps & actions I need to get SC mechanic to do? Check the brake booster to ensure there are no vacuum leaks thru the seal between the master cylinder and booster or just need to perform check & cleanup the IACV sensor, reset ECU needed? I m not sure whether the mechanic engineers can fully understand my car problem when I m trying to tell them all these issues later.
This issue had been annoying me few days while driving the car at traffic congestion condition. I really need to solve this problem with right approach otherwise I might spend more time and money of changing the spare parts without any final solution.
I hope you can provide me more concrete method & step of screening so that I can explain and lead them to the main root cause.
Appreciate very much your help and patience with me.
P/S: I tried to brake my car gentlely this morning. It seems like the choke not so obvious now. The choke also happening when I tried to reverse my car with rush braking.
