Start by removing the airbox lid and watch it run, being CFI you can watch the fuel injector. At the same time you can make sure the air filter isn't plugged, while the engine is off you can make sure that the injector isn't leaking too.

My CFI knowledge is limited, others can definitely help you better but that's a good start for you ^

I have problems with oil getting in the airbox/ breather. Could that effect my fuel throttle body in a way? Or even effect the injector. Its dumping fuel with the lid off. I mean rich. Plugs are black.

Possibly got oil into it... Maybe clogged or stuck?
Yes, like excessive oil in a throttle body or idle air controller (though I couldn't tell you where to find the IAC on these....

Definitely clean everything you can and don't route the oil vapors into your airbox anymore, I know Ford did it that way but it results in the engine consuming its own dirty oil which dusts the engine in a hurry out of nowhere and you won't know until one day it won't start and you try everything then check compression as a last ditch resort

Cleaned everything. But I found the culprit. Timing belt is loose bad. Is it just a tensioner pulley you reckon?

Is it a tensioner on this model. Making noise where the belt is.
