Ford Focus 1.6 zetec se,cutting out/misfire

hey my car is 2002 ford focus 1.6 zetec se(101hp) whit a 5 speed manual transmission
whenever i pres in the cluch after driving the engine rpm drops under the idle rpm(allmost cutting out) then it revs up to aproximativ 1500rpm then it goes back to normal idle(a bit low in my opinion )the misfire hapens at the same time but only randomly
some homework/looking at the systems:
the throttle body is a drive by cable tipe
the ignition is waste spark(3 wire coil)
the engine is MAP based
i will upload some scanner data pictures
what should i look for?

Sory for the janky ass picture this is the only way..
i think my catalizator warmed up all the way
the picures are labeld:
"cold" are key on engine off(sitting for 24 hours)
"start"are right after start up

Based on your fuel trim numbers it looks like you have a vacuum leak. Check the PCV elbow under the intake manifold (best view of it is from underneath the engine)

I taked a look they are no craks/tears on the pcv hose

If your sure you have no vacuum leaks then it could be a faulty idle air control valve, but first make sure the tps is showing c/t (closed throttle) at idle

If your scanner doesn't display this then measure the signal wire at the tps with the throttle closed is should read about 0.7 volts

Another thing to look out for on these is the crankshaft thrust bearings wear and when you press the clutch it pushes the flywheel too close to the crankshaft sensor and affects the signal.

I was thinking about the cause of the lean condition...the fuel rail was changed,long story short my idiot mechanik broke off the the plastic insert(fiting whit a 90°angle),he got one from a car junk yard that fited on it LOL,can that cause my lean condition? @steve i did not have enaugh time to look at the tps voltage(my scanner did not have data..) i re did the test whit evriting up to temp...Im suprized that it did not set a code..
