Sounds to me like your coil connections are not tight.
When the resistance reading does a happy dance it's time to get out the screwdriver. When everything is tight, you should be able to flick the termanels with your finger tip without the resistance changing.
yea the resistance was fluctuating way to easy, even with a pull on the mouth piece it would drop like 0.03 :S just scrapped it and re doing the build, going for signle coil then working my way up.
