Default strange problem:(

ATTENTION! long and hard to read/understand
So the problem is that
the car was driving ok.i stoped for about 30minutes then decided to drive agen.it started fine but was runing very rich and rough.it was hard to accelerate.
i have air/fuel monitor made myself ant switched on...the o2sensor was not working.another day i changed to antoher.the same.
i tried to pull error codes and showed that intercooler temp. sensor is bad.i found that the wires were broken.resoldered wires(later i will try to measure resistance) and tried to start cold engine (now outside 0°C) it started from 5th time only(when the car was ok it started imediatly) and i had to push pedal to the floor it idle was 400-600rpm.
the car is misfiring(somwhere in intake ) and it gets to much fuel??? .why?
i can`t beliewe that this can happen due to deffective(?) intercooler temp sensor.
mayby CSV is leaking?
all 5 injectors are new.
It seems that after sitting for a few minutes the engine gets fuel from _somwhere_.something is leaking i think.
or this can happen due to retarded timing?(i read this where error codes are explained)that when intercooler temp sensor defective this happens.
later i will try to pull error codes with resoldered sensor.
the problem apeared instantly.
Any ideas where is the problem?
what to change/fix?

Default almost solved problem....

now with intercooler temp sensor ok.
started after ~2-3sec cranking (earlier started immediatly) (i adjusted now a little co screw on in the air flow meter i think it will start better)
changed air/fuel mixture meter IC and seems lambda to work...ok...but when idle running to rich (?)
yesterday i reatached wires of CSV and WUR.
mayby this solved the problem?but looks weird :/
i "think" that my fuel consumption inreased because from home to work is about 1.5-2km...in the moorning i warm engine a little...and shows about 0.8liter earlier with the same weather (now outside ~0°C) i got ~0.6liter...
can CSV be leaking?but if it is leaking BC won`t notice.Because BC oonly shows "data" from air plate potentiometer.
Am i right at this point?

Default Re: almost solved problem....

changed CSV everything thesame.
when i start the car it runs very rich for about 10-20sec.
after that everything seems ok.
i don`t know what to do whereto look.
when i pull out oil dipstick the rpms drops a little i think that with vaccuum is ok.
when i solve this problem i`ll let you know how.

Default problem found :(

changed WUR everything the same.some breather hoses where clogged.
the problem apeared immedeatly.
after cheking everything i could..i desided to see if air flow plate moves freely...and isaw the in the air filter fuel.
o ring is bad.i changed to antoher fuel distirbutor(earlier i had thesame problem) now again the same problem.
mayby something else is bad in my car who destroys _somehow_ that o ring?
had to look again for a used FD and who knows when another will die :/hardest way to find that thing.
