Today I got my car on all 4 wheels again and took a short spin around the block to see if everything was ok.
Got back to the house and ABS inop and the air bag lite came on.
ABS I kinda expected cause I extended the wires and rerouted them for the header install.
Air Bag lite is a total mystery, did not touch any of that.
And both came on together are they connected in some way?

Good news is, I extended the O2 wires myself and deleted EGR and AIR and I don,t have any codes. I had my scanner on it for awhile and it seems to be doing ok.

 

Sometimes those lights are caused by low battery voltage. You can always check over that spark plug routing and check the ground lug that is on the RH shock tower.

 

>I had the ABS inop light on , so I brought it to the Chevrolet dealer and they reset it $50.00 . I was lucky that it didn't cost me $500.00 .
