cylinder #2, i checked all of the vac lines and all were replaced 3 months ago with silicone lines and they are all good.. i pulled them of 1 at a time to see how much it affected the idle but nothing made it better.. knew it wouldn't but couldn't hurt to try.. well i could care less if the bottom end falls out i have a spare and it would be a good excuse to build a motor the right way.. just want to get this running right... didn't get the chance to change the supercharger today, but did drive it and noticed that when i am coasting the car idle is perfect... but sitting still it is at almost 1k RPM and jumps around...
