A/C Problem In Cultus

Dear All,
I am facing a problem in my car that if the car is at the speed of 60km/h and i apply full brakes after getting slow the car shakes and sometimes even engine turn off. This problem occurs only when a/c is turned on.
Someone told me that my vaccum is not working properly.
So is he right and how much will it cost me
Regards

You need to settle your AC RPMs stably at 1000-1200. Most probably this problem related to the carburator butterfly but if the problem is not on AC then this might be a general RPM setting issue.
Tune up your car RPMs with a mechanic, ask him to first stable the RPM on petrol on 1K, then turn AC on on petrol and set AC vacuum to 1200 RPM, then switch to CNG and set to 1K, then again turn on AC and adjust AC vacuum for RPMs 1200
It will give you best car performance overall and fuel efficiency.
Also ask your CNG tech to adjust the air mixing ratio accordingly.
