I know I have a bad DOJ on my 89, and I hope to fix it this week. But I am also chasing a bad stumble. Is it possible that the vibration from the bad DOJ is causing a false signal from the knock sensor?

I will find out soon I guess.

no eperinace with efi but when my one went it put a shake thru the whole car so i would think that shake would be tranfered to the engine aswell, although somewhat cussioned from engine mounts. so yes it could

DOJ.....?

 

Honestly now, someone throw a Noob a freaking bone here!

I asked the same question, a while back.

 

DOJ = DOuble offset joint. The ends of the axle that all the movement occurs in. (holds the bearings)

The DOJ is the inner joint on the axles. Directly mounting to the tranny, and rear differential.
