91 XLT Seem's Gutless

So are you saying that the cats can get plugged on the trail and then clear up once you get moving? I was always under the impression they never really changed like that, they just slowly clogged up.

Mine do...

They'll get stopped up enough to kill the motor after about half a day on the trail.

Get out and run it for a bit and they clean off -- never totally -- but enough to run the truck down the road.
