i am getting error code 0171

i had it checked at autozone


they said it was "O2 sensor lean"

is this right?

if so, does this mean my A/F is lean?

Probobly...

Do you have a Dyno that can do A/F with sensor in place of o2 sensor ? ( the tailpipe sensors are not very accurate )

I would spend the 50-75 bucks for dyno run to see if you are lean...

Laser,

what mods do you currently have on your truck?

What year and how many miles on truck.


ANother idea is to swap the o2's and drive ti and see if the code follows the o2. It'll tell if its the left or right o2.
