New CEL's...

Well the car has been missing at idle and occaisionally at higher rpm's ever since I got it back from the dynotuner tards. I have been trying to figure out the cause the whole itme and have been largely unsuccessful.
Well today I changed my oil because I noticed the other day that my oil was almost black after only about 2k miles. I drove it around a bit and left it in idle while I cleaned things up. When I was done, I decided just for the heck of it to hook my Xcall up to it to see if maybe there were any new CEL's (as I have done already several times). I have a constant EGR code BTW so I don't know if I have any new codes unless I hook the reader up. I found I had 3 new codes:
P2196 (O2 Sens Signal Stuck Rich bank 1 Sens 1)
P2197 (O2 Sens Signal Stuck Lean bank 2 Sens 1)
P2198 (O2 Sens Signal Stuck Rich bank 2 Sens 1)
So does anyone have any insight on these codes? Could it be possible that I have bad or dirty O2's? Because I don't see how I can have a Stuck Rich and a Stuck Lean on the same sensor. I'm goinng to try cleaning them in the morning to see if that helps.
If anyone has seen these codes before let me know.

Maybe all that heat from the turbo is frying them. Its a little odd that you are getting a rich AND a lean signal from the same sensor(bank 2 sens 1). Did you delete the cats out of your exhaust?
Maybe you can get some o2's designed for use in turbo applications, I would imagine that thing puts a little more heat to the o2's than a stock engine.

I suppose it's possible, but I haven't heard of any other peeps with the same setup having that problem....
As far as having both on the same sensor, that's what I'm thinking, they might be either dirty or bad...  Yes my cats are deleted, but that would be Sensor 2 codes would they not?
If it did end up being the heat, I could probably just put some spark plug wire covers over them, because the sensors are now mounted in the collectors of my headers.

Haha double post.
I dunno I would read up on how those MIL Eliminators work and see if they would fix your problem. I have emissions here so I need my cats and havent had any experience with this sort of thing.
I would check and see if those elmi's fix your problem, or else buy some better 02 sensors.

I don't have a need for MIL's because the cats and rear O2's are just entirely deleted...completely, lol. There is not even aything to plug a MIL into. Plus, I don't think the Cat detecting O2's would cause misfiring...

Well, does your ECU know you have no rear o2's? Cause if they are just gone and it's not getting any kind of signal, and it doesn't know they have been deleted I would imagine that would cause some problems.

Yeah it knows. The codes are for the upstream sensors though anyway

What is the shop saying? I would replace them and see if you burnt them up with the turbo. About all I can offer advice wise.

They wouldn't know what to say. 
Needless to say, never go to Alabama Mustang in Cullman, Alabama.

I'd call or email VMP and see what they have to say

If I were you, I'd go back to Alabama Mustang and that other dyno place both... and challenge them to a duel. A few slaps across the face with a white glove should suffice.
Then I'd do something with mayonnaise and kiwi fruit juice which I am not allowed to mention.  |

I swear no one in the southeast can dynotune.
Anyone want to go in half with me and go to all the SCT classes and open our own dyno shop in Alabama?

Actually, I hope to be able to do that some day. It'll be a while though. I gotta get rich and move to Huntsville first. |

Depending on where I'm at financially, I would go in with you.
Seriously.

Give me some more ideas guys. Just go throguh everything that would make a car miss and we will see if I have already addressed that or if it's not applicable....Think of it as a game and whoever helps DarkShadow fine the miss gets an E-cookie.

RWTD in mobile would have prevented this problem assuming it isn't a bad sensor. They know their shit. VMP isn't too shabby either and they are in the south east. Amazon Racing is somewhere in SC which is also in the SE. They also know their shit and are one of the premier tuners in the country.
You just needed to ask about shops and/or be willing to drive a few hours ( depending on where athens is) to get the job done right. I think your statement is better stated as "No one in the near vacinity of my house can dyno tune".
As for your problem, for a sensor to read rich one second then lean the next has to be a result of one of 3 things I can think of (keeping in mind I am not a master tech)
1.) Sensor has shit the bed
2.) Fuel is not being delivered in a consitent manner cause the A/F to bounce all over the place...you should get on a dyno or get a wide band commander and monitor your A/F during a pull.
3.) There is a massive leak somewhere in the intake track introducing a lot of unmetered air into the system or the MAF meter is fouled or pegged causing the computer to do weird shit trying to maintain proper A/F.
