Hooked up a vacuum gauge to an unused port under the throttle body today.
Idle in gear- 15.15.5in
Idle on nuetral- 16in
Part throttle, full throttle- 0
Any throttle position, including just enough to keep the car moving at a steady pace- 0 but builds to about 10in slowly.
What are the numbers it should be? All #s except full throttle seem pretty low to me.
