I bought a vacuum gauge today and hooked it up. I thought that the vacuum was supposed to drop when the throttle increases, but instead it increased. Did I get it wrong, or do I have an issue?
Here's what I did:
Test 1
Hooked up the vacuum gauge to the heater control valve vacuum line. Pulled about 20" at idle, and then I had my assistant give the engine a little gas. Vacuum went up to 21" or so.
Test 2
Hooked up the vacuum gauge to the brake booster line. Pulled about 21" at idle, then 23-24" with a little gas.
Thanks!
