I have skunk 2 stage 2 cams and cam gears and a b18c motor...
My idle is really lumpy. When i brake and come to a stop...the idle sometimes drops to 300rpms and bounces back up 700. Most times the car shakes and comes back to that idle of 700rpms. Other times the car will actually die. Any idea on what this could be?

 

i think your cam timing is off. verify cam timing and valve clearances.
