Ok my meter doesn't read Hz, so I just set it to volts. I found on a site that 2.5 is the normal reading at idle, and that it should change. I got the 2.5 but no change. Is this a correct test? If so it would seem my MAF is bad.

I just went out and tried that test on mine. At idle, it showed 2.62 volts. If I goosed it, it went to 2.61 volts. Hight rpm vs low rpm no change.

Sorry about that MoUse, I accidentally copied the wrong page, that was not for the 3.8L, to test the functionality of the MAF you need to be able to measure for hertz. :/
You can test for voltage and ground though.
http://easyautodiagnostics.com/gm_ma...gm_tests_1.php

Cheapest multi-meter I seen that will work is this, there may be others, but this is recommended on the article.
Amazon Amazon


I do know how you should be able to get an idea if the MAF is functioning properly, go to an auto parts store that scans for codes, ask them to scan for codes for you, and while they are at it ask them if you can see what your MAF readings are on it, in like 2 clicks they should be able to have that info up, you won't see the hertz it is operating at, but if you goose it a bit you should see it change its g/ps readings.
At idle make a note of the readings, my MAF was bad, and it would only be a tiny bit off, nonetheless it was dipping low enough to start giving a cylinder 1 misfire code, it never gave a MAF code though, which was odd.

More than likely, they only use the pocket scanner(which won't see live engine data)

I thought some of them have decent model ones, the last store I went to had one that looked like mine, I have an Actron CP9575, maybe it was actually an older model..

Yeah, around here they only have pocket scanners.

I'd have to go to a mechanic and pay for a diagnostic for that.
