Avalon hybrid injection nozzle issue

I had something similar with my Avalon. Are you sure it's the injection nozzle? My car experienced rough idling and a drop in performance. Turned out to be related to emissions. Maybe check the fuel system?

When you say fuel system, do you mean like a dirty injection valve? Because that's kinda what I was leaning towards. What exactly did you have to do to fix it?

Yes, probably the injection valve! I went to a workshop, they cleaned everything related to the fuel system. I'd recommend doing the same, you probably need someone with the proper tools and knowledge.

Thanks for the insight! I took it to a mechanic, and you were right. Turns out the injection nozzles were indeed very dirty, causing all the problems I described. They cleaned the entire system, and the car is running smoothly again. The whole thing cost me 515€, but it was worth it to get the performance back. Thanks again!
