My car has been having trouble starting in damp weather, and slight misfires... So I'm out there checking my plug wire resisteance.

My Chiltons book says that a wire between 0-15 in. should have a reading between 3,000 - 10,000 ohms. So naturaly I check the easy #1 wire first and it's roughly 15 in. but I'm getting a reading of 1,000 ohms... so then I checked my #3 wire which is about 18 inch (so should be between 4,000 -15,000 omhs or something) And I get the same reading of about 1000 ohms..

Am I doing something wrong?? Does a LOW resistance cause problems at well??

Thanks!
