I own a 2007 vitz. Today, I got it's battery changed since the old one died. The new battery is AGS 60 CNG(my car is on patrol). After the battery change, the car has started to vibrate violently in idle. In neutral, park or in drive without pressing the accelerator. As soon as I press the accelerator, the vibrations stop and starts behaving normally. The car was fine this morning, the problem started after I got the battery changed.
Also, I cleaned the air filter while I was at the shop. I have checked if I hadnt replaced the filter correctly but it seems fine.
Experts please tell me what to do now.
