controls air flow as it enters cylinders. slows/speeds up air speed depending on conditions ie idle

Could this be the reason why my car stalls on cold start ups?

It controls the secondary butterflies within the intake manifold, right at the head, on both SOHC and early DOHC KAs. If it's not opening you'll loose a lot of airflow, but that would nothing to do with stalling/hesitation.

these are butterfly valves. no idea if they are swirl control valves. the bulb looking thing is the thing that opens and closes the swirl valves.

Nice way to confuse the thread.

The swirl control valves are the butterflies. Just like I said. Nissan calls them that.

Not sure how a picture confuses things. No reason to be threatened by a picture, my friend.

It doesn't have SCVs. Neither do late '93 and all '94 models. But it's easier to just remove the butterflies from the rod, take the rod out, and plug the hole on the far end than tracking down another manifold.
