Ses P171

[DWSmooth]

Terry,

I read in a previous thread that the code P171 (lean bank 1 I believe) is something a lot of people get. I just started throwing that code now after 3+ years of all the same mods? You mentioned it might be a air leak before the SC, do you have a good place to start looking?

Mods – 2# lower, K&N, JBA shorties, chip (Superchip), magnaflows X pipe, E-fan, etc.

Thanks,
David

There was a thread saying it could be a dirty MAF element and try cleaning it with electrical contact spray. The hoses under the throttle body and PCV lines are the most common culprits.
