8 codes after the rebuild ????


Hello again, I just got done with the Top and Front rebuild and runs like a champ with a bit of a crappy Idol for some reason. I am getting 8 codes now as follows.
1--P0174-- bank 2 system to lean
2--P0154--oxy circuit no activity detected bank 2 sensor 1
3--P0401--exhaust gas recirculation flow insufficient flow detected
4--Po111-- intake air temperature sensor 1 circuit range / Performance
5--Po107--Manifold absolute pressure circuit or barometric pressure low input
6--P0174--bank 2 system to lean
7--Po154--oxy circuit no activity detected bank 2 sensor 1
8--P0401--Exhaust gas recirculation flow insufficient gas detected.


Any thoughts before I go Ripping things apart again... Thank You for all your help in this matter. Note how I get the same code 1 & 6.

 

OK, I am running some cataclean and top end lube treatment through the system and will keep yas posted.
