Passo RPM drops on Idle

[seismic84]

Dear fellas ,
Am facing strange issue by the past 2 weeks , i have Passo 2007 Racy 1.3 . During Idle state its engine rmp drops to the level where engine dies . during night when i switched on head lights the condition becomes worst . Lights goes dim and high and engine seems breathing in and out rpm goes up and down .
i have visited the mechanic but still not fixed.
1.Battery is fine
2. Alternator is fine

Need your suggestions please.

My pleasure. Do other services as well. These three services must be done after every 40k kms.
