Coil Packs

[osageorange4]

Does anyone no if there is a certain Ohms reading that I should get when I test a coil pack with a multi meter . I have been getting a P0300 code that I have been attempted to fix to no avail to this point. Put new plugs in , changed a O2 sensor that was bad, checked the fuel pressure also and it was good.

I would say check the FSM, but experience tells me that a coil pack can be bad even if resistances are within spec.

You could bite the bullet and purchase one, then swap it out with each coil pack one-by-one until the problem goes away.

Of course, if you have more than one bad pack, this method won't solve your problem. :/
