Mazda 6 Engine Problems
Hello dear Mazda owners.
I have a Mazda 6 2.0 16v LF engine 140hp and I have big problems.
There is no throttle response when engine is hot but when cold I have a little bit of response. When there is throttle response and I hold the throttle evenly on high rpm the exhaust manifold glows red hot and smells rotten egg.
I uploaded a video on youtube so I can show you guys and in the description I wrote everything I done to the car so far.
Here is the link

You also may have sent catalytic converter bits back through the EGR valve an in to your intake damaging cylinders, or connecting rod bearings.
Good luck. Check catalytics, do a compression cylinder test and go from there. Check your oil pressure. Check for oil in coolant, coolant in oil as well. More things wrong engine is done.

That leaves us with guessing. You don't tell us how many miles are on the engine, I assume there are plenty.
Things I would do:
Get a fuel pressure reading.
Check for vacuum leaks. Don't forget the weird ones, like the O ring under the oil filler cap, PCV grommets and so on.
Clean the MAF sensor.
Clean the throttle body.
Clean the idle air control valve.
Clean the EGR valve.
Replace the PCV valve.
It sounds like a lot of work and it is. But you will know your engine in the end.
There are how to videos on Youtube for just about any of the tasks that I listed.
Do some of that and report back.

I think you will have to redo all of that clean up work in order to find what's missing.
Who has done the work and what testing procedures were used? How many miles ago was the work done?
And one more thing: consider replacing the ECT sensor with a known good one.
