I was just browsing through the Service Manual (www.helminc.com) for my '92 Si, and noticed that it said the lower portion of the throttle valve is heated by engine coolant.
I always hear that cold air helps performance, so is this warm throttle valve inhibiting performance? Anyway, I can't figure out why it would need to be heated.
In case you don't know, the throttle valve is inside the throttle body, in the airstream, and it rotates out of the way when you press accelerator. Sorry, just making sure we can all join discussion.
Has anyone ever heard of this? If it doesn't need to be heated, wouldn't it be a good idea to plug the hose that sends coolant to the throttle body?
