I have a few Pony Express CEL Fixes for the EVO that I need to get tested out to determine if they fix the P420 CEL (or even the P139).

I need 3 people who actively have the P420 CEL to BETA test the fix. I'll send them you agreement form for you to review and sign, then out goes the CEL fix + instructions. Install it, test it, and report back on it. Nice and simple.

Contact me via email if you are interested in testing this product out or post questions here.

 

I have the 0420 right now, I just went to Autozone about four hours ago and had them pull the code. I HATE that damn CEL!!! I will e-mail you as well.

 

Why use electronic fix? I have a solution that is mechanical with no wiring necessary.

 

...ya its called a MIL eliminator, plug it into the or sensor bung. making it all seem so technical...

 

Yup... It's a MIL Eliminator / CEL fix / whatever you want to call it...

Nothing major about it...

Looks like I have 1 spot left... anyone else wanna be a BETA tester?

 

I've been working with Dan a Pony Express. I tries their WRX MIL Elim., It threw a lite (P0139).
Dan sent me their new STI MIL Elim.
I installed it yesterday, no light so far. I'm going on a long road trip this weekend. If no light by Sunday, I'd say it works. I'll post on Sunday.
It's simple to install, only one wire to cut and splice the Mil Elim. in.
Best way to access the wires is:
Move passenger seat all the way back,
flip cut section of carpet under seat by the console,
Unplug the O2 sensor,
use a screwdriver to pop the plastic/rubber plug out, (push down),
Go under car and remove O2 sensor for easy work on a bench,
Install in reverse.

 

Currently I am getting a cell as well but I don't know what the code is so I will go get it checked out and see if I can help. I would really like to take part in this because I want to get rid of that damn light as well. I can't stand it when somthing doesn't work right. If I dont get to take part I will be first in line to purchase one of these for sure.
