Replace the intake manifold. There's a reason why the rods in front are made of plastic, they act as mechanical fuse.
Means your intake runners are jammed. From there you have very real possibility of the runners breaking and entering the engine, destroying it.
Seen it a few time.... Just get a new manifold and install.
