Aoa.. I need guidance on one issue of my cultus 2014. I feel engine is making more noise as if I am driving car on 60 in first gear i.e more roar of engine when it crosses 50. RPM at idle are around 8000 as usual and but I am feeling my car is bit heavy and making more engine sound with normal speed. I have also visited CNG wala for setting but same issue. Can you guide me regarding this?
