Two different 4.6's?
Two different 4.6's?
I called autozone to see about an O2 sensor for my truck. Told the guy I had a 4.6L and he asked if it was the 280ci or 281ci engine. I know ford makes a DOHC 4.6, but I thought both engines were 281ci's. My truck is a 97, I looked under the hook but didnt find anything, I think the autozone guy is a crack head, what's the real story?
