P0171 CEL - Due to tuning?
Today I drove out to lunch, stopped to get some gas and my CEL came on.
I checked it at Autozone and it is a P0171 code.
I don't have a CAI, just the stock airbox. Do you think the error could be attributed to my dyno-tune/reflash last Friday? It is much warmer today and the Santa Anas are blowing. So I don't know if the outside temp or the wind conditions have anything to do with it. I disconnected and reconnected my MAF sensor. I also checked for loose vaccum lines but didn't find any.
So could this be a problem with the Tune and the temperature ?

it should be because the fuel cant run the AFR you want it to run. the injectors are only able to make a correction of about +-5%. so when they try to tun your AFR and cant do it for whatever reason (leak etc...) then the CEL comes on.
oh and search for a thread about that CEL. lots of good info there.
