i am going to be putting on my pacesetter LT's tommaro morning and im looking at my truck and i have 4 o2 sensors and the headers only have 2 holes for them what should i do?????!!!

 

The rear sensors are just there to monitor the cats and make sure they are doing their job. Are you putting on an ORY as well? You can either buy O2 simulators or have the rear O2's disabled in your tune.

 

yes i am putting the ORY but i dont have the simulators or the tune yet so should i unplug them 4 now?

 

Yep, it will trip your SES light but won't affect anything else.

 

plug the fronts to the headers and leave the rears unplugged and go get them tuned out

 

if you have the money to spend on the tune, thats your best bet, but.... if a tune isnt in your future yet, i think i bought a pair of casper electronics 02 simulators from summit for 86 bucks. they worked, light went out for a little bit, but eventually came back on, we are talking about weeks passing, but... no issues with a light, its just a light! like said above, rear o2's only monitor your cats and make sure they are doing what they are supposed to, nothing more, the fronts acctually make a difference with your fuel. and how rich or lean you run.
