DTC 463 and 507 after LT and magnaflow exhaust install Okay, need some help here. I just did Pacesetter LTs, catted Y pipe, and Magnaflow catback exhaust. Car is idling high and has hissing sound coming from front of intake. Codes are PO463 and PO507. I do not have rear O2 sims in it yet, just the original upstream ones from the manifolds with homemade extensions. I have only drove down and back a block and it is idling high. Any ideas?
