code p0171 banc 1

Raced a Camaro lastnight and the car fell on its face for a split second and picked back up in or around 3rd gear....First time it's done it to me.


Next morning drive to the grocery store got what I needed and got back in the car...started it and got the (CEL)....


Recently had a eurocharged tune,K&N filters and secondary cat delete about 2 weeks ago.


Any suggestions on what may be the culprit???


PCV?? MAF sensor??


I was told if it was MAF sensor that I would also have a "banc 2"

S550 on order
did you tell jerry to disable the sensors that were taken out with the 2nd cat? ..K&N's are full of oil

This is the #1 thing I see no one do, tell the tuner what mods they have, they just think a off the shelf tune will work fine but it won't..it's for a stock car, with stock everything.

I let them know what I had done to the car when I went up there
I didn't know there where sensors for the secondary cats...I thought just for the primarys. Yes I did win though,lol!!! Camaro ss with a tune,cam,intake and exhaust....beat him byabout a car and a half....should've been by more but the car leaned out and fell on its face.






How ever I did run a srt jeep this evening and had no problems...car ran fine
