Need some help on this one. I just installed my exhaust system, from the headers all the way back. A few days after install the check engine light pops on. I checked the codes and got the 2 bank errors. Leads me to believe my o2 sensors aren't reading right, maybe running rich now. No real driving issues but, have noticed a loping idle, it drops almost to the point that it serms like it'll stall out but never does. I'm no mechanic and I'm sure my cats aren't messed up, what can i do to clear this code? I know the tuner will do it, but thats just tricking the computer. Any help is appreciated.

 

I do believe that your 02 sensors are not in the same spot as the stock exhaust system.
Anytime you do a full exhaust,....it's a good idea to do the tune. Why install a full exhaust without updating your car's computer? It's almost futile.
Good luck man.

 

That's the plan, kinda difficult to keep droppin' money into my car with a 7 month old. Fortunately, i have an understanding wife, just oredered my tunes and tuner from MPT.

 

Awesome.
Good luck and let us know how you make out!
