I heard some talk of people having trouble with dirty MAFs. I'm not talking about the chump that stole your girlfriend that summer; I'm talking about the sensor. My car idles a bit rough sometimes (and uses a bit more gas than I'd like), even after a complete tuneup. I'm just starting to consider that it is either my MAF or O2 sensors. Do MAFs ever need to be cleaned? Thanks again.

 

They do get dirty and can be cleaned. But be very careful not to break the wires. I take a biss card and tear the corner off and use this to clean the wires. Not a big piece just about a 1/4 inches from the corner small piece and wipe the wires off. Just be carefull and you should be fine.

 

If you want to test your MAF then TAP it with a screw driver and if your RPM's start to change then its your MAF. I believe your engine light would come on if you had a problem with the O2 sensor but you can lways try it anyways. Its wierd when I disconnect my batter froa bout 15 minutes I will get better gas mileage, thats after I change something on the car.

 

my car idles rough and i get bad gas milage too, my maf has prolly never been cleaned, and i dont know how to.
How do you clean it? i got the biss card thing but where is it

 

i use a qtip and some electronic parts cleaner its near ur right hand inner fender mine had two ant-itamper torx head screws holding it down just unplugg it and unbolt wipe gently with a qtip!

 

yeah the size you need to get the maf out to clean it is 20 tamper proof bit. i got mine at autozone and the brand is Great Neck then it says T-20 star bit

 

sounds like you need a tuneup on that car. Have you checked the plugs on that car and see if it burning normal. Also a clogged fuel filter will give you problems too

 

Qtip use alcohol or brake cleaner. After that go for ride and you will be blown away how good your car runs

 

you really dont want to use brake cleaner. brake cleaners are know for leaving a residue.
