Long tube headers are not legal in any state due to relocating the cats is against EPA rules. Removing the cats is also against EPA rules. I doubt that any legitimate web site will help you break the law. Good luck.

Get it up on a lift and check your wiring and make sure you haven't melted your O2 sensor wiring on your headers. If it's not your wiring there, check to make sure your ECM has a good connection.
Call me illegitimate but I'll help you as a car enthusiast. We talk LTs on here all the time. Hell, I have them. Mea Culpa, Mea Culpa.
You have bad wiring, bad connections or your PCM is in trouble.

hello eboggs_jkvl:
thanks for the feedback. i have already replaced the harness for new ones, i even check the connection and they look right too me. i have even rotated the sensors and harness and the error codes always shows up.

all this started happening after i burned the previous harness and sensor (from bank 2 - passenger) due to the heat coming from the new headers. and now the codes wont go away and there no more smooth idle and driving.

If the wiring and the O2 sensors are cleared as the problem, the information that I've read points to the ECM.

Check to make sure the ecm can see the rear 02s even after your wiring job. It still has to see them even with them tuned out.

Actually, the ECM needs to see the front O2 sensors to operate correctly. If it can't, the car runs like $hit.
