By-Pass Air Control Solenoid problems

[Dessertrunner]

As I mentioned in a different thread I am having some issues with the idle on my car, It will run perfect some times but others will sit at 2,000 rpm and nothing can get it down. I blocked the hose to the Auxiliary air control and there was no improvement. Next I blocked the air supply to the By-Pass Air Control Solenoid Value and then went for a drive. As you can image the car would not idle at all but I could control that we the foot throttle. What I found was that this solenoid is the problem with the idle.
A interesting side note is that the car accelerated a lot smoother then before as well as the throttle being far more responisive. It is very difficult to drive the car with no idle but I suggest some of you try it. The best thing is that over the years I have found that when you are cornering hard it is as important for the engine to slow down quickly just as much as speeding up. When driving in the mountains the brakes are always fighting the engine because the revs haven't come back far enough when you need breaking. Now the car is 5 speed I think having a responive engine is even more important.
The SVX value has a spring rotor which is not directly driven from the ECU but bounches back and forth. I wonder when we are accelerating hard if the solenoid could be working against the engine. I would like to find a way to do with out it or get a latter type fitted that gives better performance. By the way I blocked the hose with thick electicial tape and wire ties so it wasn't sucked into the engine.
I look forward to your comments.
