Minimal Vacuum at idle

[DuckMan]

Chris,

Thanks for the info, I guess the MAF goes back to Pro-Flow. In your reply, you mention verifying the blower is not making boost at idle, how would one go about doing that?

I did drive the car today and found at 65MPH, which translates to about 2200 RPM, and the throttle completely closed, eg. foot off the pedal and coasting, it will pull only about 10-12 inches, while down shifing, eg off-ramp, I'll see about 20 inches. Cruising, steady state, we're back to the idle numbers of 0 - 2 inches. I don't know if this provides any additional information, but I thought I'd list what I saw this morning. At least she idles, poorly, but idles now. Thanks again, I appreciate the input.
