So i get my car back last night after about 3 months of being down. Damn rod bearing... Either way, the idle was dipping low but no CEL light. On the drive home it came on. Ive been driving it under 4K to break it in. The comes are P0170 and P0172. I also have an exaust setup with TP. Including the o2 fouler. What are these codes and what can i do to fix them?

 

Anyone???

 

P0170 Fuel Trim (Bank 1)
P0172 System to rich (Bank 1)

Sounds like the ECU is having trouble adjusting the fuel amount in closed loop mode. I would imagine that it could be many number of things sorry I couldn't be more help. I would check anything that had to with how much fuel is delivered or how it is measured.

 

Thanks. I have the shop manual at home but i'm stuck at work until 5. Anyone else?
