I would like to ask for your help. I have an 2006 Focus ST, and few days ago, little water came in the engine at the symposer's place. It has a bad sound after it warmed up. I checked the plugs, and changed all, but after one week the problem didn't go away. When it's cold, it run perfect, after warm up a little bit, it start like misfire, when I floor it, it's like lean. Sounds like traction control.

I don't know where can I find the problem. No fault codes. I checked with forscan, but I didn't find anything.
Drop a link, how does it sounds when idling.

Thank you!
