On my engine, the regulator
On my engine, the regulator is on the spider inside the manifold. Is it accessable thru the opening in the top of the manifold after the throttle body is removed?
Can't get to the regulator
Can't get to the regulator through the opening for the throttle body. If it is on the spider, you will have to remove the (plastic) top part of the intake manifold (upper intake)to get to it.
