    That's actually a pretty good idea, my vacuum is lower than it should be, I will check the hose behind the intake manifold and see if I forgot to reattach it, as soon as it cools down

    i followed the ls rocker arm torque procedure, once you have set everything to zero lash, you should only be able to crank the torque wrench so far before getting to 22lbs, if too far than you need a...
  12. 2 misfires on crank, normal? should I even care?

    I get 2 misfires when cranking pretty consistently, but not in the same cylinders. Cranking doesn't seem to be affected, and I am wondering if this is just from the mods, or if this is causing damage...

    I am pleased to hear you got it fixed by removing air from the base running airflow, I would recommend you check out your idle settings too. Your minimum idle settings are actually above your base...

    You think bad plugs are causing half my cylinders on each side not to fire? The plugs are brand new, and the half that is not firing look brand new, like they are not getting gas either. It's as if...

    OK so not all my cylinders are firing. I pulled the plugs and only half are firing. But i get no codes other than failed maf that i intended to get.

    Is this a sign of a bad ecm?

    That's exactly what I was wondering, if the ecm crapped out after 100 or so flashes. And sorry for not answering the prior question, the vacuum is correct at idle, it bounces around with rpm, when...

    Would a blown head gasket cause higher map and lower vacuum?
