What all this codes have in common is that every single one of them can be caused by a vacuum leak, so carefully check for cracked, loose or disconnected vacuum hoses, wiring to the coils, fuel pressure regulator, fuel injectors, specially on cylinder 2.
NOTE:After cylinder cut-out system is turned off, the system monitors (through misfire detection) if all intake and exhaust valves are open again.
NOTE:Misfiring may be caused by many faults in the fuel injection system. Usually a misfiring fault is stored with faults pertaining to other components. An engine mechanical fault could also cause a misfire condition.
Good Luck!! A HELPFUL - 4 THUMBS - rating for this solution would be greatly appreciated. Thank you for using FixYa.

P0100 is a MAF circuit problem, check the connector to the MAF sensor, look for water or signs of corrosion on the connector pins, if no problem is found you may need a new MAF sensor. The P0170 is lean fuel control condition and is related to the MAF problem.

What you have is a real mess
You have so many different codes that aren't
even related, that I 'am not going to list them
You need a repair shop or dealer
You have air flow,couple oxygen sensor,cam sensor
speed sensor,real nightmere
I would look for something simple or some common
I have no idea where I would start on that
Obviously, I would have to road test & use the scan tool
to check data, but I think all those codes are squed somehow
eg: not doing you any good

The code P0170 means that the air-fuel mixture coming in to the engine is too lean, or too rich. Usually it's the lean condition that causes this code. The code P0173 means the same, only for the Bank 2. Some car manufacturers list the description for the code P0170 as self adaptation out of limits.
The code P0170 could be caused by a number of reasons, such as vacuum leaks, bad PCV valve, or other parts of crankcase ventilation system, low fuel pressure, bad oxygen sensor, bad MAF sensor or even a bad EGR vlave.
