I have a code P0305 and I'm doing a process of elimination.
I want to test the coil pack, but I don't know what a good resistance should be...anyone have that?

Also I need to know which leads to test...not sure if there's 3 or 2...if only 2 no problem...LOL!

I guess I could test one of the other coils and hope its ok, but would like to know what the starting point should be.

I have checked the spark plug & wires and both look good.
I don't see any vacuum hoses disconnected, so I don't think it's that.

Hopefully it's not my injector, as the dealer replaced it about 5 months ago, and I really don't want to have to change that knowing I'll need to remove the IM.


Thanks in advance!

Just move that coil to a different cylinder and see if the problem follows.

You can measure the resistance of the other coil packs. I don't know if that is going to work anyway, I'm familiar with inductors (that what this is), and it is usually insulation that starts to fail at high voltage levels that slowly drops the max V output of induction. This was mainly due to heat. But modern materials are usually not better (but safer) so that is why we still have failure even though the coil is only 1/8 as busy. Nothing wrong with some polychlorinated biphenyls and good old fashion asbestos.
