Hi everyone. I was driving on AC/CNG and suddenly one rear coil crashed. I got it fixed and one by one other 3 had to be replaced. As per today I have changed all rear coils and spark plugs and got car tuned. The issue I am facing is that race (accelerarion) is not 100% responsive. Sometimes when I leave acceleration, the rpm doesnt come back and car jerks slightly. On AC, the situation is worse on petrol even. When accelerated the pick of car varies as sometimes it just slips oit of hand and sometimes it loses initial pick. This seems like a chronic issue now because its been like 4-5 months since it started. TB washed also but no help. Advice needed guys
