Intake manifold had a crack leaking a small amount of antifreeze towards front of motor. Replaced intake manifold with a brand new one. Since replacing, car runs very rough, though all injectors are working as well as coils. Car ran amazingly smooth before swap. Any ideas? Definitely not a first timer on turning wrenches but I am stumped.
