I don't think the lambda or O2 sensor would affect the idling speed. Maybe you should check or clean the MAF sensor or the idle control valve. Just thinking out loud...

Hello! I did a little experience: change the MAF. The idle problem is solved! But NOW i have a new problem: when the car is in N and do a hard accelaration the engine look like a boxer one. If i do a gentel accelaration the engine revs normally...

PS: I miss my JAP'S...

You may want to take out the throttle body and clean the paddle with carburetor clean. Sometimes the paddle gets sticky due to oil or gunk depsit.
