Vacuum gauges? Explain please...

[deftsound]

I was thinking of buying a pillar pod for some aftermarket gauges and found a triple pillar with 3 gauges. One of hte gauges it came with was a vacuum gauge. I got to thinking, why exactly would one want to know what the vacuum pressure was at? Anyoen know?

I got a autometer Vaccum Gauge, It reads Throttle Postion, and Load on Motor. Mine Reads about 23 At Idle.

but cant you judge the throttle position by how hard your pressin on the gas and by the rpms?

a vacuum gauge can be a very valuable tunning and diagnostic tool. a vacuum reading can tell you alot of whats going on in your engine. ie: late valve timing, late ignition timing, stuck valves or lifters, burnt valve(s), intake leak, blown head gaskets and many more.

cool thanks

i was kinda thinkin about getting an air fuel gauge, seems like one of those would be pretty helpful for knowing if your cars runnin rich or lean

if your getting the A/F gauge get the wide band that needs to be placed at the midpipe
