  1. I need some help I just put ford racing Cylinder head Hot Rod cams An intake manifold on. An after I got done the car want idle I can take the Hose off the intake Manifold An create a vacuum leak an it idles fine but it Through Check engine light and it said bank 1 an 2 are running lean so can any plz help
  2. Do you have a tune installed, that is written for your mods?
  3. Yea has a bama tune 4 every thing I've done
  4. Well if it through a check engine light after you took hose off a lean condition is not uncommon for vacuum leak.
  5. I've look for leaks around the Manifold Sprayed Starter fluid around it to see if it would rev an nothing I'm out of things to try
  6. 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?
