It's kind of a cool thought experiment though. Even if it's completely impractical.



I do agree this is a much better route. A V3Si would probably do the trick without making the noise.

That's a decent point about the throttle hanging, but assuming the TPS is accurate, the log does not show that as being the case.

I'd tend to agree. If this is a brand new symptom, the IAC may need cleaning. That's probably the first thing I'd check. Next would be a vacuum leak that has developed.
