Seeking advice: Loss of power and rough running in 2019 Toyota Etios petrol engine

Hey, I have a 2016 Toyota Corolla, and had symptoms like this too. The same error message, hissing, loss of power, everything. The diagnosis was a leaking intake hose. Seemed like it was a serious problem because the engine can't breathe properly and that can be bad for a lot of other components. In my case, they had to replace the whole intake hose to fix the problem. That was it, and after that my Corolla ran like brand new again. So, in my experience, yes, you might be right in your guess. Hope you get everything fixed!

Hi, thanks for your reply! That actually sounds almost exactly like my Etios. I'm relieved that you seem to have found a simple solution. Do you perhaps remember how expensive the repair for the intake hose was in the workshop? And have there been any other complications with your Toyota since the repair? I'd like to be as prepared as possible before I speak to my garage again.

Hello, don't worry, I still remember it well. It cost €100 to repair the intake hose on my Toyota Corolla. Since the mechanic sealed the hole in the intake system, I haven't noticed any further problems with my car. Everything has been running great again since then. I hope everything goes just as smoothly for you!

Thank you very much for the information! That really gives me some relief. 100€ is not as bad as I had feared. As long as I can solve the same problem and get my Etios running normally again, it will definitely be worth the money. Thank you so much for your help and encouragement. That was really helpful!
