Question on Vacuum Gauge Readings
I have a performance problem on my 93 Honda Civic. I asked a question about it in this post.
https://www.civicforums.com/forums/2...ml#post4682380
The symptoms on the gauge are
--Fluctuates rapidly by 1Hg all the time.
--At idle is at around 21-22Hg
--intermittent drops to ~19Hg at idle
--When the engine is shuddering the vacuum fluctuates rapidly between 0Hg and a normal 'under power' value between 5 and 15Hg
--If you let off the throttle quickly the vacuum only climbs to around 24-25Hg
Thanks
