Running rough after glow plugs?

[Nonturbo]

Ive got a 97 7.3 now. I replaced all 8 glow plugs today. Put everything back together. It fired right up but idled a litte rough. Then it ran rough going down the road also. Acts somewhat like its skipping but just dosent seem rough enough to me for that to be the problem. Cant be sure about that though Any ideas what would cause this? Could it be a wire that got pulled lose under the vale cover?


Thanks, Austin

You may need to check to see if one of the injector connections got disconnected. If you don't feel like removing the valvecovers right away, you can use a DVOM from the center pin on each valvecover connection to each pin right next to the center pin to see if any are open circuited (should get about 2.8 ohms I think for each one). Cheers!

Probably hit some injector wires in the UVCH. Check the plugs and connections.
