Hi Everyone, Recently had a tune-up done on my mitsubishi lancer efi (CK1A) car to address a vibration issue it was experiencing while idle. However, since the tune-up, I've encountered a significant drop in fuel efficiency. Before the tune-up, my car was averaging around 10-12 kilometers per liter, but now it's only managing 5-6 kilometers per liter. This drastic decrease in fuel efficiency is not only inconvenient but also costly for me. I'm reaching out to the community to see if anyone has experienced a similar issue or might have insights into what could be causing this problem. If anyone has any suggestions or solutions to improve fuel efficiency and address the vibration issue, I would greatly appreciate your input. Thank you in advance for your help!
