1996 f250 7.5l....od light flashing...

[W-T-Katt]

Hey all, here's one for ya. Can a bad wire leading to the o2 sensor cause the od light to flash as well as causing the truck to have no power (chug & sputter) when put into gear? It idles fine. I'm 99% sure it's a bad wire somewhere because when I get under the truck and jiggle the harness that goes to the tranny, transfer case and o2 sensor the light will stop flashing and the truck will be fine until a hit a bump just the right way. I'm just trying to narrow down which wire may be causing the problem.

TIA,

Figured it out. It was a loose connector where the harness connects to the tranny. ;-)
