I have codes p0202 p0203 p2196, when i go to ford dealer they told me i need a new engine because cylinder #2 is low in compression only 17%, but the report they gave me doesn't show the code p2196.

Code P2196 indicates a rich condition. My guess is that raw fuel is passing through the non-firing cylinders is the cause of the rich condition and will probably be corrected when the engine is repaired. You can't chase a rich condition when you have a poor running engine.

I was getting a P2195 (O2 sensor stuck).
After following this tread and others I checked the PVC and cleaned it.
Then removed and checked the ERG with a vacuum.
Now all is well. Not sure what it was. Engine runs smooth and does not
set code. I too first replaced the O2 sensor. What a waste.
