    Do you have a tune installed, that is written for your mods?

    Well if it through a check engine light after you took hose off a lean condition is not uncommon for vacuum leak.

    Let me get some more info from you.....will it run with a little throttle? Does it run than idle lower and lower until it stalls? Did you make sure all your sensors are pluged in? Did you install cam phaser lockouts? Are you still running variable cam phasers? What else was done besides cam swap?
