I've had my CEL light come on now twice with these codes. I'm not sure what's causing these codes to be thrown. The first time it came on was a week after flashing to my 93 performance tune. The second time was directly after flashing to my 93 tow tune. Both times I've been able to clear the DTC's and they didn't come back. Anyone with any ideas on this? Thanks in advance.

 

I would think M.T. should be in the loop on this so he can take care of any problem with the program.

 

They've been in the loop since the afternoon it first occured. I just wanted to get opinions/ideas from other board members to see if anyone else had encountered anything similiar.
