I think he means it didn't fix it.

Interesting. I've only had experience cleaning "young" MAFS that aren't too dirty. I'm afraid to use brake cleaner, as I've seen what it can do to paint - I know I know, paint is different material from the sensor... "but I still can't help but wonder..." :p

Residue is one reason to be careful of some electrical cleaners, as they may carry "lubricating" material, if one doesn't read the label carefully!

no, the check engine light isn't on. nor was it on. I shoudl go and see if that bulb even works. The idle, and tranny shifting did smooth out.... Maybe I"m just hypersensitive and noticed it while it was still in spec....

Since Arthur is paying attention I will ask this:

Does disconnecting the battery reset the adaptations to 0 or just reset trouble codes, or both?

Noting that the check engine light isn't on is meaningful information only if it works.

Ok

Next test is to turn key to Run position and see if you have a CE lamp [ do not start car]

If yes, then you can still get cdes from the 38 pin DM with a Led Tool.
If no, then you can't

Is car a Cnd version???

When that car wasn't running, I turned the key to the ON position. The light didn't illuminate... Does this mean the bulb is burned out?? Or does this mean that there is no problem??
I have always tried to let my instincts tell me if something is wrong. I don't rely on technology, but find it useful at times to let me know...

Car is a canadian version. Without the check engine light being on with the key in the on or run position, does that mean there are no codes to read??

It means you have no CE b/c ytou have no N/59 module or bad bulb..that is what we are tryting to determine , but you have to answer the questions.
The ??????????????? is " Is the car CND version.???? "..Yes/No

Yeah...ya know, when you get someone to answer , it would benefit you to answer the questions in RESPONCE...

So , the Reason for my Cnd ? was you don't have a CE cuz you don't have a N/59 DM [ Diagnostic Module.]

By disconnect, you have reset the ECU Memory to mean, so that means you may have a condition that will come back..the suspect would be FP reg or Vac leak.

If the Maf was bad, I would nor expect instant remedy by simply reset.
Drive it and if the condition repeats, then get codes.....

Sorry, Arthur, I shouldn't have been rude.... I appreciate your help.... Without the N/59 DM, does that mean that I cannot use the LED blinker tester??
What's a FP reg??

Would an OBD2 code reader diagnose the engine problems in that car?? The port that's under the dash??

Go to that site I posted and look your chassis up for code info.
The FP reg [ fuel pressure] has a vac hose On it..pull the hose and see if any fuel is evident in hose or FP port..if yes , replace it.
And lok for vac leaks.

Unmetered fuel OR intake air will screw up the adaptation and the Maf can not correct for it cuz it is unmetered. So, you thi9nk that the maf is bad, but that may bot be the case if you have a vac leak or FP reg is leaking fuel into the intake...and since those two are very common on 104 HFM systems and take 5 min to check, that is what I would do of I were you.

Where is the fuel pressure regulator on that car?? Also, what is the best place to pull a vacuum from to check for vac leaks??
