Etios reduced engine power after chip tuning

I had similar problems with my Etios. Was there any chip tuning done?

That's interesting. Yes, the previous owner mentioned some chip tuning. Could that be the cause?

In my case, it was. Faulty chip tuning can mess with the engine management system. I would suggest a workshop to check it. It might save you further damage.

Thank you! The workshop confirmed it was the chip tuning. The repair cost was 180€. Now everything works!
