This is on my '94 Centurion. 460 FI, I've been running rich and getting poor mileage since I did my header swap.
New cap and rotor.
New plugs, burn pattern was good on the old ones, just old.
New plugs didn't make any change that I could tell.
O2 sensor was not changed when I did the headers, but I was wondering if it could contribute to my problem?
I've gotten some conflicting answers on if the sensor was bad it should light the idiot light in the dash, others say no.


Any thoughts?

I haven't had a chance since getting to OH., just getting settled and unpacking tools, I left a lot of stuff back in Idaho that was supposed to come with, but didn't get loaded. :doh0715:
