I just ordered a set of pacesetter lt's and ory, going to install them this weekend, now i have some 02 sensor questions, im guessing i will install the front 02's back into the headers, but the rears are going to have to hang, im getting a custom tune, but it will probably be in a couple of weeks, i know the truck will probably run rich, but is it gonna run like crap? am i going to hurt anything? i mean comeon, whats the worst that could happen...

 

The rear 2 don't do anything but make sure they cats are working. Just unplug them and you'll be fine besides the SES light being on.

 

fast truck, and fast response...thanks man
