Yeha i've considered getting an O2 simulator. My main concern is the extension of the 02 sensor. Could this be the reason im gettin a CEL? I thought they were all good and sealed up. Should i just try the o2 simulator and see what happens?

 

Can you show me a pic of where you ran the new wires. I know that sometimes when you extend wires it messes with the signal it sends. Like on my 300zx I accidently mangled the detonation sensor wires when i was swapping the injectors and it put me in safety boost. Me and a nissan tech tried to put the wires back together but since he had to use new wires it messed up the signal and my only choice at that point was to replace the whole harness.
