Hey guys, i have an auto repair shop and i have a customer who just bought a mustang and wants to bring it back to stock. It was tuned for e85 and had lowering springs and intake runners deleted. Customer did the mistake of buying an older model intake manifold that has different vacuum lines than the original. Just trying to see if anyone has managed to make this switch around work. The only codes I’m getting are that the runners are stuck open. If anyone knows the correct vacuum set up for the conversion or should I just give up and tell him to buy another intake or runner actuator assembly. Thanks in advance
