I have an issue with my cultus 2015 almost driven 118k, the issue is, low Acceleration knocking in high rpms during driving and also low fuel average around 6-7 with Ac... When i shift 2nd gear the car
seems to be in under heavy load.. Almost zero Acceleration.. Then rpm goes upto 2.5-3 car starts knocking till next gear change. And at idle rpm is stable but there is delay in Accelerator response when i accelerate car at idle the response is late.
At idle when i turns on AC the car jerks continuously after some seconds.
I went to a mechanic he checked every thing adjusts the tappeds after checking injectors and plugs he asked me " the piston no 1 is not working properly may be the valve is leaked or else"
Kindly guide me and share your opinion what i do
