Cylinder has spark but not firing..

so you ordered another Intake manfold before taking the old one off to confirm it has a crack....

I think the head is cracked...and it is not the one on the engine....lol
We already know this lol. Ya i bought it used from someone on this site a while ago. Still waiting for it to be shipped :wack: I kind of wanted a new intake anyways because this one has some stripped threads and looks pretty tired. Plus, the intake runners and ports on the performer match up a little better than an LD4B on a 360.
