intake manifold making a pop sound inside

Just swapped a ls motor into a eg hatch, it just started making a popping sound inside the air intake or manifold, also my battery wont recharge, alternator is good, and checked fuses, and it still wont charge.

Re: intake manifold making a pop sound inside

lean fuel mixture, valve timing, ignition timing, and valvetrain problems can all result in popping back thru the intake.

Re: intake manifold making a pop sound inside

most common mistake: spark plugs are in the wrong order.
second most common: timing belt is off a tooth.
