Hello I have the same car and the same exact problem I don't have volt testers or anything but my MAF SENSOR GOES OUT WITHIN A MINUTE IM disabled DNT have money to do ALOT I've bought some online through eBay for 20$ first one lasted 4 months then I bought 2 backups from another distributor and these threw a code in 2 minutes I tryed both of them then got out first one cleaned with MAF SENSOR cleaner cleaned out air box and throttle body inside and out with the MAF SENSOR CLEANER it did fine for 5 miles then threw code runs like crap rough idle no power backfires car shakes has 202000 miles on it has brand new cat and oxygen sensor bank 1 . For the life of me I can't figure it out , I've worked on cars and done complete restos for 30 years or more as I understand the ecu is also in the air box ? Any and all comments welcomed DNT nd ignorant ones ither .
With no volt testers, we can assume none of your MAF sensors have been tested both before and after installation.
Do you have bleach smelling exhaust?
P0107: Irregular low MAF voltage towards PCM
Strikes me as a wiring issue.
While we're here, how many miles on your current spark plugs?
Is your engine supercharged?

It'* wiring. Need to load test the circuits to find the area of high resistance.
These will run OK when unplugged. The PCM uses other inputs to control fuel. It'* not as good but they will run relatively good.
When they don't it'* wiring.

I think they mentioned trying AC Delco and Delphi, AC Delco is what I'd have went with.
I have had non OEM sensors cause issues for sure on my old Park Ave, good point Mike.
Any oiled air filters used?
If so you are careful not to over oil it I hope, that can cause MAF issues also..
