No rigging things to make it work. Second is at 56k my cylinder head decided to spit out the spark plug from #1 cylinder. Got that fixed. Third is now the butterfly flaps inside each runner are all up. If they break anytime soon they will get sucked through the head and down into the block then it will eventually blow the bottom end. Fourth is I have some weird ass sound coming from the head. I believe the valves are up and get stuck sometimes. I think this because when it happens my exhaust sounds like a damn sti. But for those butterfly flaps it is a known issue but Ford just won't recognize the problem. The Mazda 3 shares the same intake manifold and they had the same issue and they put a tsb and recall out for it. Ford just wants to make more money off us. They want me to replace the whole manifold assembly for $208 which is stupid because euro 1 supply has the replacement flaps for $111 shipped.
I pull the manifold off & remove the flaps altogether, & fill the hole on the end w/ part of the shaft end cut down.
