Headers installed, now check engine light is on
Will this be remedied by a tune? Have it schedule in about two weeks. Is it okay to drive until it's tuned with the check engine light on?

I'm pretty sure they did ziptie the O2 tube, but I'll take a look underneath and see to make sure. If I go to autozone or someplace like that they should be able to pull the codes right? If so, would they be significant, considering I have no knowledge regarding this matter?

Hey man, just pull the codes out of the DIC. Press and hold options, and then press fuel 4 times (I think, this is from memory). See where the the codes are coming up, probably PCM, and the codes will tell us if you are having O2 issues. Did you install bungs up front and install both front and backs?
One set can be turned off in the software by the tuner, and will take care of the codes. Good luck man and let us know how we can help.

I have intake, headers (w/hi-flow cats), and exhaust, and once in a while at low speed driving I will throw that code. I have never had a tune, either. Clear the code and don't worry about it. Have your tuner turn off the 2nd O2's like most do.

I pulled this from a site - it's easier than it sounds!
1. Turn the key to the ON position, but don't start the engine.
2. Clear any messages displayed on the DIC by pressing the RESET button.
3. Hold the OPTIONS button down and press the FUEL button 4 times. The computer will automatically display all the codes it has created. It will cycle through each code every 3 seconds.
Note any code that ends in H is a history code indicating something that has occured in the past but is fine now.
Once the computer has finished going through all of the codes, press RESET to enter the manual configuration mode. It will start with a module and show "NO CODES" or '#CODES".
To clear the errors, once in manual mode, press and hold RESET until it displays "NO CODES". Press OPTIONS to go the next module. Repeat this step until you reset the codes in all the computer modules.

I get the P0420 code which I believe are the same. I have cleared the code twice but it keeps popping up. I have a thread in both the Z06 section and C5 Gen. Hopefully, it's something that is either covered by GM or my warranty.
By the way, I can clear it and then dive my car for awhile and it pops back up. So something definitely isn't copesetic there.
