97 Explorer Sport 4x4 missing

[brushhippie]

Just got this truck and its got a bad miss, hooked it up and it throwing missfire on #4 cylinder. It has new coil pack, plugs and wires, can a bad injector make it throw this code or am I looking for something else. Thanks....This is the v6 model

Check the compression first, then look at the fuel injector. Yes, a faulty injector can cause a misfire.

Just for giggles you might change the #4 plug anyway ( while checking the #4 compression) -and swap the wire with another( be sure to swap both ends-lol).

If the code goes away the plug was bad, if it moves the problem is with the wire.

New parts can be bad out of the box, so do consider them in your troubleshooting.

Oh, and be sure to triple check yourself on the firing order on the driver side--we all get em mixed up and could have sworn they were right.

This is the most common cause for bad miss-
