Re: 1994 4.0 OHV Running Poorly
I checked them in the most redneck manner possible.
I did the old "spark jump to wire" method, which may or may not be more reliable than taking an Ohmmeter to it.
They all appeared good. If you have a different recommended method I am willing to try it.
Even if all the coils were bad though, it would not affect that vacuum leak or low fuel pressure, I do not think. And those I believe are probably the major causes of the shitty running of the truck.
Still though, like I said, willing to try anything to help.
