Hell of a test lead!

It is awesome.

Works great on everything from under the hood to trailer lights.

I think mine is still in the camper from when we went to Kansas last fall and I really don't want to unload it and pop it up to just to get it out.

So yeah, running around Omaha it felt like it had kind of a rough idle. On hills right before it would downshift it felt like it had a miss.

I know changing the plugs had been discussed but I don't think they had been, so to start there I got a set coming. On fridays I get off at 11 so I broke my son out of daycare early and we got to work.



My help didn't last very long...



Changing spark plugs by feel is fun!



Plugs did not look horrible but tested terrible in the tester



I would say the plugs are pre my FIL acquiring the truck, I don't know if they are original or not but I would say it is plausible with only 77k on the truck. I have never seen plugs this clean externally... but I live in a dirt bowl. Wires are Motorcraft as well.

And yes I did go back with Motorcraft plugs, by dumb luck they are the same part number.

And the bottom of my left forearm seems to be full of fiberglass from the stupid heaterbox insulation.

I ran all over and bought the last air filter in town that fits a 1991 Ford Ranger... at Napa.
