Error code P0171 P0170 and P171b came up
So I recently installed my avo turbo and it was all working good up till 3 weeks later when error codes p0171 and p0170 popped up. I than refreshed the the ecu and the light was gone for a good 7hrs and the the p0171 came on, and this morning the P0171, P0170, and P171b came up. Its basically saying my car is running lean and rich. When I installed the turbo I noticed the gasket that connects the over pipe to the rest of the exhaust had a slight gap in it. I highly believe this could be the issue. I cleaned the MAF sensor, checked all the vacumme lines, checked for any signs of leaks. I've been keeping an eye on the afr using the raw data display through torque and it's been acting kind of funny, like it wants to stay at 4:7:1 but every now and then goes a little lower.

That leak (Over Pipe to Exhaust) is post O2 sensor, so I am sure that isn't causing the problems. It should only be at 14.7:1 at idle and while cruising or at light throttle. Are you running an AVO basemap? Have you done any logs with EcuTek?

A code P0171 may mean that one or more of the following has happened:

Hows the idle? afr 14.7 and boost at -18 is what mine says. I also have the avo base map and if anything it runs rich when getting into boost. Always goes right to 11.2 which is the lowest I think the ecu can register so probably really going lower than that. It's worth it to pull a ecutek log and you don't even need to do WOT pulls to redline to get something useful to look at. |

No problem. Tighten up the nuts as best you can and run it. I don't remember if they are locking nuts or not, but perhaps you could add a lock washer.

That depends on what caused the gasket leak.
I mean no disrespect at all, but did you forget to tighten down a header bolt initially? If so, then your header is probably fine and once everything is re-tightened down properly it should be okay until the new gaskets arrive. If you did install it 100% correctly and it blew out a gasket that early while throwing codes, I would take a look at the header itself before anything else.
