NEW UPDATE all codes are gone now after losing ice.
Misfire is still active problem.
I have put in:
-new spark plugs denso OEM
-new coil;s after market
-clean MASS sensor (using special cleanar)
it was runing couple days ok until aftermarket coils started acting.
shortly after got P0301,P0304,P0306,P0302,P0305.P0303
took aftermarket coils out and resistance was about 35 times less compared to OEM old coils.I have put old OEM coils back with new spark plugs and car was running better,but still in the morning at cold start just got P0300 twice.
After is warm up no misfireing.
-beside that I did oil regulator valves 4 of them cleaned and inspected as well as two knock sensors.
this is getting interesting .........anybody has any idea what could be next to do???what is causing misfire at cold start?

Related to the oil leaks you mentioned above, you could check the PCV valve and the two ventilation hoses (12261-50050 and
12262-50090). Sometimes some of them are broken and could cause problems of vacuum or pressure, affecting when the engine is still cold or idle.
