what is the sensor that is plugged right into the side of the airbox next
to where that MAS is hooked up at? I can’t tell if that one has it or not,
But my 2000 grand marquis does.

AFAIK only the MAF sensor is in line with the airbox tubing. you got a
picture or something of what it looks like?

You could try cleaning the MAF and see where that takes you. If this
doesn’t help then you may need advanced diagnostics…

Question for you poster: I have a 2000 Mercury Grand Marquis with 70,000
miles on it, runs great. However, 6 months ago there was a torque converter
slipping issue that was correctly with anti-shudder fixer. It went away,
but then a month later I starting feeling hesitating again.. It doesn’t
feel like the torque converter though, it feels like firm air issue. Could
this be a sign of a dirty MAF sensor?

Is MAF sensor failure &O2S failure the same?

Do you have to disconnect the battery?

adventureoflinkmk2 says:

Nope, just disconnect the connector and you’re good to go. 🙂

adventureoflinkmk2 says:

Not necessarily. Sure the symptoms can be similar, but there are different
check engine codes for each of those sensors. Additionally other things can
cause “failures” in those systems; vaccum leaks, timing faults, etc
