trouble codes po137,po157, and po405.i know the first two are O2 sensors and probably need replaced.the last is some sort of EGR code reading low voltage.i did just install my slp lid and filter, but figure there is no relation.Any answers to my prob?

Low voltage to bank 1 & bank 2 rear sensors, if you have long tube headers that could be the reason.

EGR probably means you have an egr problem

po137,po157

Are you running no-cats or gutted cats? IF so you need to disable the codes with your tuning software.

po405

Do your headers have provisions for EGR? Hooked up/in use/blocked?

I don't have headers,but i wish i did. factory manifolds and cats.

Honest to god truth the p0137,p0157 are only going to tell your car if the cats are physically on the vehicle or overheating (clogged). I would buy/install an offroad y pipe then turn off the reporting isntance on both codes in the editor.

p0405 - just turn the reporting feature in the editor off for this thing. EGR is a bia' hastle!
