cleaning a MAF on a Sentra

Hi i have a 1994 nissan sentra and because of hesitation I want to clean the MAF sensor. Does anyone have a guide
on how to do it?
i tried the online guides but they are generic.

Click on the link below, and use only the product in the image to clean the “MAF’. Make sure to follow the cleaning instructions on the can exactly. Don’t touch the contacts on the “MAF” with your fingers or a rag. They are delicate and will get damaged. If the cleaning doesn’t resolve your issue, tell us in detail exactly what your issue is.

The exact stuff I just used. DO NOT BLAST THE MAF CLEAN. Instead just lightly 'rinse' it from a distance.

There are other minor things to do that may help hesitation.
What else have you tried? What's the car doing?

sorry i should have explained.
1994 nissan sentra 1.6l ga16 engine. 155k miles.
she has been a great car no oil loss just rusting to hell.
I get hesitation when i hit the gas. the engine doesn;t rev nothing increases then it will make like it's going to install then it goes. basically from a light is hell.lol

i pulled a plug and it looks clean not fouled. i replaced the fuel filter. i'm cleaning the maf sensor now. When i pulled the maf sensor i noticed a crack on a vac line coming from the black platic cube-tray right underneath the air intake. i cut the bad part out and pushed it back on. i'm letting the maf sensor
dry then i will reassembel eveyrthing.

unfortuantly money is tight this month so i'm trying to hold off bring to a garage.

Last tune-up was when?
Were “NGK” plugs used?
Have “NGK” ignition cables been installed recently?
Has the fuel filter been changed recently?

With an “Engine Vacuum Pressure” gauge rule out vacuum leaks and post results.

Use an “In-Line” spark tester to confirm spark delivery to all the plugs and post results.

Use a “Noid Light” to confirm all the injectors are firing and post results.

If you’re running a “K&N” oil soaked air filter remove it and put back the “OE” air filter after cleaning out the air box.

Fuel pressure PSI values are below. They must be confirmed with a “Fuel Pressure” gauge. Post results.


Fuel system pressure with regulator vacuum disconnected (43 PSI)

Fuel pressure at idle (43 PSI)

Fuel pressure with vacuum connected (36 PSI)
