Motor skipping

I've recently purchased a '96 f-250 with a 7.3l powerstroke turbo diesel. Truck has 300,000 miles. The truck ran well once it started Really hard to start after sitting for a day or two.

Since I didn't know the maintenance history I decided to start with changing the glow plugs among other things. I did the passenger side 4 and now the motor skips.

If the plugs weren't screwed in far enough would this cause a problem? The cover is just sitting on there now and I am going to take it off to check the wiring. I suppose one of the caps could have come off or is not seated. Other than that, I am at a loss as to what could be the problem. These are new Bosch glow plugs from NAPA.

Thoughts?

Yank those NAPA plugs right out and go with Motorcraft plugs. Go Motorcraft or International every chance you can with these trucks.

You most likely knocked a connector loose. If it's the original harness and gaskets then they will most likely need replaced since they are old and brittle at this point.

The plugs are Bosch. Good or bad?

So i went back in and reseated the plugs. Runs good now plus I let it run for a bit. The test drive went well. When I work on the other 4 i'll know how they should be connected properly.

Yea, it's on a diesel truck, but it's just wiring. You just have to make sure connections are good, wires aren't bare, and pins aren't burnt.
We can help you with the diesel part
