Good Evening. You did the right thing cleaning the honeycomb, you should try cleaning the elements on it. It is a very good first step to try that, however if it is kicking on a check engine light feel lucky because the MAF sensor can do things that will also not kick on a check engine light. my words of having been there before would be to replace the sensor. Hope this helps, and if you have any more questions please feel free to ask.

Where is the mass airflow sensor located on a 1997 Buick Skylark 2.4 liter


Right off the air box its the first sensor on the vehicle .
The air is sucked through the air filter then goes through the mass air sensor so its in the air duct .
They have a spray can cleaner you have to remove the clamps and connections and remove it .Spray it with the cleaner some times it works .
Its a rather expensive part but its vary important because it is the first sensor that the computer reads to adjust all engine controls .
Also don't through it away you will get a lot for the re core value.

Tip

How to resolve a mass air flow sensor code : ALL vehicles.


How to resolve a DTC , p0171, or p0174 code. This code usually does not appear on your vehicles dash, but rather a "check engine" light will display.
If you have an OBD II reader,( some auto parts centers will allow you to borrow theirs) plug it into your vehicle (usually under the passenger side dash) and pull the code.
This code usually means that your MAF ( mass air flow sensor) is reading the air/fuel mixture and senses a problem or may be dirty.
There are a couple of things you will need to solve this problem.
- You will need a can of mass air flow sensor cleaner, and a screwdriver.
Step one : Depending on which vehicle you have you must locate the MAF.
It is usually inline on the air cleaner intake or air "box".
Step two : Unplug the connector from the MAF, and loosen the hose clamp holding it tight.
Step three : Pull the MAF out and be VERY careful DO NOT drop it !
Step four : Make sure you are in a well ventilated area, and place the MAF gently onto a clean rag or absorbent towel, spray the inside of the MAF that looks like a honey comb, and make sure you DO NOT touch the small sensor wire !
Step five : DO NOT dry off the MAF it will dry quickly, re-assemble and test out your vehicle, we usually hear people tell us they notice a difference right away in the performance of their vehicle.

98 windstar #2 misfiring running lean obd says


Is this a 0174 code ?
You need to clean your MAF sensor with Mass air flow cleaner. Remove MAF from intake tube next to throttle body, inside looks like a honey comb, there is a thin wire, do not touch, just spray it clean, let it air dry.
Clear code, test drive
