ran codes again and now got 0171,0300,0301,0302,0303 and 0304. Found some black stuff on manifold area and at base of couple of fuel ignitectors. Would this be a probable cause for this codes?
Running out of options...

P0171 is a lean condition. Look for vacuum leaks, low fuel pressure, weak fuel pump, check the PCV hoses and connections as well as the intake hose.

Any unmetered air entering after the mass airflow sensor can cause a lean condition. This is also the likely cause for the misfire codes you have, the p0300 through p0304.
