I have a Williams game with 11
Z-30-1800 coils (32.9 ohms per coil chart). Three of the coils are only registering around 11 ohms (the others are all around 33). Do these coils need to be replaced?

Coil Sleeves - should metal sleeves be replaced with plastic sleeves for improved performance? Also, should existing plastic sleeves be swapped out with new ones?

Thanks for the help

Yes.

When you replace them, use current sleeves. If they are working leave them alone.

If the coil sleeve is binding, replace it. Cleaning them is usually a waste of time.

Make sure you're measuring them 'out of circuit', eg, with at least one lug disconnected, so make sure nothing is messing with the reading. If that's the case, then yeah, replace them
