I need to do a Vacuum test.

I have the Vacuum test tool already. Now Im just looking to get the meter.

Which model you got? I found a few on Amazon already just want to know what kind of meter you guys use for doing the Vacuum test.

Thx :)

engine vacuum or pulling a vacuum on a vacuum operated device?

Any digital multimeter will work.........

Engine Vacuum. I have that already. :)

oh ok. thx

Im just going to get it, use it, then RETURN IT for a Full refund. LOL !!!!

I need to check mine as well, just out of curiosity

^get a meter, i wanna find out my vacuum as well. haha

I bought the connection from Rosenthal, just need a multi meter. Tim has one, we can check the vacuum next time you're over.

Good Stuff! :)

I just wish someone that I know has these kind of meter ...

Maybe I should ask around ...

let me know if you perhaps could do it for me too! ;)

How do you use a multimeter to check vacuum?

Search is ur friend

alz0rz, oh hmm ... never really thought about radio shack ... if I have time today im gonna go check it out :)

why in the world do you need to buy a multimeter and the connection from rosenthal when you can buy a $10 vacuum guage or mechanical intake manifold pressure and 3 feet of hose and be done with it??? :eyetwitch

also last i checked, there was no table to equate the voltage from mazda's tool to an actual pressure :eyetwitch :eyetwitch

nycgps - If you can check my vacuum pressure at the same time, I have a multimeter you can use sound good?

true a mechanical vacuum gauge attached to the vfad nipple or intake manifold would work too. with a mutimeter you can check the vacuum lines and for leaks i believe. more to an extent. either would work fine.

Well, Im trying to find out the correct value for "fail/pass"

So just hang on :)

the mazda's vacuum test tool only shows certain "voltage", So like rotor said, there is no way to tell if it "fail" or "pass"

Trying to find out the correct value right now ...

without the factory correlation data on the output signal relative to altitude I don't see how the factory tool is of any use, nobody has yet to produce said data as far as I know :dunno:

thats why Im kinda confuse right now.

Hmm. My engine stalled the total of "3" times for the past 5 days. I just drive, redlight/traffic, clutch in, rpm going down then "poof/stalled"

No good. But like I said only 3 times so it might not happen when I go visit a dealership ... *shurgs*, same thing for the rpm "dips" around 500 rpm, it does not happen every time.

oh, no premix btw, pretty much like what has happened to swoope's old motor a while ago (premix = no stall, no premix = no good)

not my old engine. the new one after 35k miles..

but i know what you are talking about.

pm me or give me a ring..

wait. fukin search newb!!!!!

beers :beer:

still old engine now !

YOU fukin newb ! :rofl: :rofl:

this sucks ... I hate it when I know my car has a problem, but might not be able to get it fix cuz it happens "randomly" :(

YOU fukin newb ! :rofl: :rofl:

send me a pm. i think i know of what you are fighting..

i will give you some steps.


hey, but what do i know.. i am old!!! might have oldtimerz!

beers :beer:

just put a vacuum dial gauge on it, less than 15mm/hg in NYC likely = fail
