Open loop to closed loop switching after header install
Not sure why but after I installed a set of new jet hot coated pacesetters the car seems to tun smooth and then rough. I hooked the scanner up and it's jumping from closed loop to open loop now. It will jump back and forth every 5 seconds or so. Any idea why?

well I have an extension on one side but the other is spliced. The thing is it was spliced before I had the headers on and it was fine. This all happened after the new headers. when I first got the car it would do that but then I found out that the wires for the heaters for the O2s were cut so after I ran new heater "power" wires it ran great. I just went out and checked to see if it is still getting power to the heaters and they are fine. So nothing has changed other than putting the headers on. I wonder if I damaged them swapping them from the manifolds to the headers or did the header coating do this?

Replace the O2s and you should be good to go.
