Hello I’m driving a 2007 ford Taurus sel 3.0 and when I accelerate my car
putt . When I start it and drive my car shakes very fast but only under the
hood….

Simon Black says:

NEVER use carb cleaner to clean a MAF sensor! You have to use MAF sensor
cleaner only! 

Sam Scott says:

very good thanks- 

Kyle Maes says:

EVERYONE! I used brake cleaner, as soon as I installed it again the car
didnt idle… It idles now but sounds like its cammed lol. Got a new one…

Joel Devonish says:

What if the MAF is wet? what would cause it to be wet?

INeed Vaseline says:

And umh. I think that umh. Maybe this video has a little to many.. Umh what

Travis A says:

use CRC electrical / mass air flow cleaner

chupalia says:

Brake cleaner works just as well as maf cleaner. Electra clean is better,
but please don’t use carb cleaner.

mark rohyans says:

Use CRC Mass airflow sensor cleaner.

greenbull56 says:

you should not have to unless their is a issue with it. you really shouldnt
have to touch it unless it is needed or if your cleaning it which doesn’t
need to be done often

Deejay SantaCruz says:

used mass air flow cleaner as recommended!!

towrecker says:

HOW STUPID , YOU DO NOT USE CARB CLEANER ON THESE , IT WILL DESTROY THEM ,
THERE IS A CLEANER THAT IS SAFE FOR USE ON THEM , IT’S CALLED MASS AIR FLOW
SENSOR CLEANER , AND IT’S LOCATED LIKE 2 TO 3 FEET FROM WHERE YOU PICKED UP
THAT CARB CRAP !!

scrimmo says:

Do not ever spray carb cleaner or any solvent on a MAF sensor like this guy
has just done. A MAF sensor is a sensitive electronic part which requires
electronic contact cleaner or MAF cleaner. Carb cleaner contains a lot of
crap which will leave a residue and destroy certain plastics and
electronics. Don’t do what he did.

TheArfdog says:

Pretty sure this guy didn’t mess up the MAF with carb cleaner. Pretty sure
it worked when he put it back in the car.

raquelglo says:

perdoname snopyyyy

GGGG761 says:

i have both carb cleaner and maf cleaner and in the back of the cans it
looks like it has the same shit but who knows

Ben Henderson says:

my truck is misfiring on several cylinders and i have replaced coil packs
and its still not fixed could this be my problem?

snipingshadow says:

this is kinda like old timers telling you to use wd 40 on your guns. dont
do it.

lilseip-B14 says:

Maf sensors r very delicate an touchy if u remove it the way he did ur
twice as likely to damage it removing whole unit helps prevent damage plus
cleaning the unit whole prevents any containments from braking lose an re
clogging maf sensor

Julio Marckwordt says:

@scrimmo You’re absolutely right!!

bizzyfingers says:

@HunterCO1 i work as an electrical fitter for the traction and rail
industry. thats why i know of it. our manufacturer uses the ULS version in
a white tin. I did not have to search on google, there is no need to be
defensive mate. Im not a threat, i just like to help people, thats all.
Peace, BIZZY

grimreaper9292009 says:

no no no . you should weld your hood shut. you should never spray carb
cleaner on a mass air flow sensor . thats why they invented “mass air flow
sensor cleaner” unless you want to blow it out when have to spend $200 on a
new one. they are very sensative, water,temp,vibration can all destroy one.
and never touch the element. the oil on your hands can wreck it, just like
you should never touch halogen light bulbs with your fingers.

BlueRice says:

also get it tune up. check for vacuum leak and tune the air and fuel ratio.

NSTASY says:

what is a great site to buy auto parts for cheap?

papasmurf1086 says:

@nidinc does it hesistate when after 2500 rpm? Cold be your catalytic
converter clogged. Have someone hold thierhand behind the tailpipe andgive
it a rev. if no incresed flow when revved then there’s your problem. or you
cn take the exaust off before the cat but that is quite loud. if the cat is
clogged it will jump to redline quick without it on. ad the same problem.

cullen9017 says:

would break cleaner work

jettarulz says:

Bosh mass airflow sensors usually are already split no cleaning required 🙂

James Davis says:

To Webby19861, You can bypass the MAF, you can buy a resitor. If you have
any questions about what you need you can conact me. I will check back on
here and see if you or anyone would like to know how. It is cheep and easy
to do. Wish you all the best.

emanxavier says:

I dipped my MAF Sensor in Johnny Walker Black, and the problem was fixed
and the car ran great. for 10 seconds

cdwheezy says:

Use dedicated MAF cleaner, they sell it near the carb cleaner

Barry Holtzkener says:

I am sre the actor said milli ohms when measuring resistance!

Layla Crowned Lable says:
