Redtop BEAMS idle (VVT problem?) Options

[WHATxTHExTIFF]

I am currently having problems with my redtop beams motor, it seems to have idle fluctuations almost as if I am revving the motor vroom vroom and then it drops , and sometimes it drops so low as if it's going to die then picks back up. Sometimes when I startup the car is sounds as if something is grinding. I have replaced MAF sensor, checked all the vacuum lines , and I have tried swapping out vvt and the problem still persists. When the vvt is disconnect when the car is running, then the idle raises but no idle fluctuation then. Does anyone know what the problem may be? I think it may be something with the vvt since when disconnected it doesn't fluctuate? Thanks in advance

Also it seems to lag during acceleration
