Just to make sure Im not crazy (CEL light Question)
Just to make sure Im not crazy (CEL light Question) I just installed Pacesetter longtubes tonight, along with a new set of NGK TR55's and MSD Plug wires. 2 things. 1, since I havent made an extension for my front O2 sensors yet, I just screwed in the back ones and disconnected the front ones for now. Im pretty sure, but not 100% sure since I couldnt find the instructions to remind me, but you need to run the FRONT O2 sensors, and put O2 simulators on the rear ones, correct? Also, since I DONT have this setup correctly, this would most likely explain why my CEL came on after my header install today? Just wanted to double check...motor isnt running funny at all, no noises or anything - just that. Oh, and I assume you do NEED O2 sims on the rear 2 O2 sensor spots, correct?
