I recently bought a 03 max not running , just needed a clutch . Long story short I got it running but it was running rough later found out that bank 2 had low compression so I got a 08 motor swapped in it got that one running but it was still running rough checked the compression and its good but bank 2 is completely dead checked the coils and tested for spark in the spark plugs and everything is okay tested injectors and they are fine ! When it had the old motor I remember the crankshaft position sensor was connected with the o2 sensor on bank 2 sensor 2 so I checked the o2 reading and they aren't reading anything but I have new cats and new sensors could it be that the ecu got messed up since the crankshaft sensor was connected with the o2 connection ? Need help a lot of money to just give up !! But idk what I could possibly do to it anymore ! It has everything new but the ecu

 

Both sensor 2 not reading and bank 2 sensor 1 is a lil to rich <br/>
