Well, you've probably noticed by now that things look a little different around here. You are a keen observer!

The whole site is new and that includes all of the software that drives this forum. With probably over 10,000 settings and hundreds of back-end programs trying to talk to one another, there are bound to be a few glitches that we haven't discovered yet. So, if you happen to stumble upon anything that just doesn't seem right, give us a shout and we'll try to sort it out.

Thanks for using the VCOA Forum and enjoy the new look!

Bruce,

The air reg you have acts just like a thermosat and it senses engine temp from water passing through it, hence the hoses. The regulator is open when cold and slowly closes as the temp rises, which restricts airflow until it reaches about 145 deg. where it should close fully.

It allows air to bypass the throttle valve, boosting rpms. As the engine temp reaches operating range, the valve closes the bypass and the engine should idle properly.

What happens over time is the air reg valve becomes dirty and sticks or freezes in the cold/open position and will not close.

As a quick fix attempt, you could try boiling it clean or soaking in a solvent parts bath. Worth a try.
