Dear all,

Asalam o Alikum,

I recently bought Cultus VXR Model 2006. I've two main problems facing with it currently.

1. It gives black smoke when i start it in the morning on petrol, but after sometime it gets fine. This problem started a few days back. Earlier there was no such issue.

2. RPM is not constant. When i switch on AC, RPM goes to 2x1000, when i switch it off, at times RPM drastically falls around 0 or at times it stays constant on 1.

I'm a new owner of car and hense do not have much information about it. Please guide me what could be the cause of it and how it can be fixed.
