n/a_threat

Ever since I started putting aftermarket exhaust on the stang my cel was coming on with a code of po153 aka upstream passenger o2 sensor reading slow. I talked to ford, and numerous mechanics and exhaust installers, no one knew what was going on. The dealership even put 2 new o2 sensors in and it didn't work.

You guys are going to yell at me for this one!!!

I always knew that I need to change the intaketo get better flow, but haven't had the funds. Early last week I decided to do something that all stang owners do as soon as they get their car home for the first time, take the air silencer off. Yes, I've had my car since Oct of 2003 and still hadn't taken the silencer off, not sure why, always knew I should. What the hell do you know, the cel turned off!

My advise now for the first mod, cai!
