mass air flow?

ive been reading the posted threads about maf cleaning,and went to the store and bought some gunk maf cleaner,opened the hood and looked for the typical maf sensor sandwiched between the intake pipe and the filter,and dammed if i could not find it! uhhh mind if i ask where it is

its on the throttle body.. you will need a torx screw driver to remove it......... it is a rectangle black box with 4 wires going to it............ take the screws out and pull out carefuly...........

its on the left side middle

um, i dont know what "left side middle" you're refering to but AFAIK the MAF sensor is not pictures there. it goes in the hole right above the TB opening.
looks like this on 95/96 rivs and a little different on 98+


be very careful cleaning it b/c a new one can set you back ~$200

i see the mass air flow

i thought that was the IAC valve?

well first of all...... i dont think this is the throttle body off of a L67 sorry about that.. i just typed in L67 throttle body and thats what came up........ but yess that is where the general location of the MAF is BUT it is on top and has 4 wires going to it ALMOST positibe its yellow, green, blue, red....... or along those lines

GOOD luck robotennis61....... Git R Clean

thanks people! who wud a thunk it?

THERE IT IS

thanks Jason

Here's my throttle body after a good cleaning. I went as far as to remove the butteryfly and polish it with some Mothers aluminum polish. Came out real nice.

actually, what you circled is the TPS (throttle position sensor). The MAF is the empty hole in the middle near the lower part of that picture. That's a picture of the TB with the MAF removed!!

OOOPS.............. mistake takin.......... i should have noticed the screw holes........... SORRY MR. RIVIERA!!!!!!!!!!

its cool

it's all good, just wanted to make sure you knew what you were looking at

i got it! it came out pretty easy, and looked clean enough...but after cleaning it ,and reinstaling, i did notice a better throttle response,just tapping the peddle in park......only thing left to do is instal a cai........and cat delete.......

Take the whole throttle body off and clean it. You won't believe how much better your car will run.

u bet....thats on the menu too......!!!

150k and I've never cleaned my TB. Somehow, mine still manages to idle pretty well.

Aaron, when you get the time take yours off and have a look. It seriously only takes about an hour to do the job. Just buy a new gasket before hand and your set. You won't believe all the black crud and carbon that is built up in the throttle body and up into the super charger.

you would be surprised how much a little layer of carbon can effect. the difference in throttle response is amazing. it was one of the first things i did to my car when i bought it back in 2005. now,rather than taking it off, i just remove the MAF screen, open the butterfly vavle and look in there with a flashlihgt

Yeah, I need to do this. How much coolant do you lose when taking it off? Should I lift up the car on the driver side?

if the car is completly cooled off then you may loose a pint. i think i took of the cap to loose some pressure before taking off the TB. nothing a little water cant top off.

Maybe a 1/2 once at the most. No need to lift up the car.

Hey guys,

I'm experiencing some engine choke after I start the car when it's at idle or in park. It sounds like the car is getting ready to stall out. After I rev the engine at a stop or once accelerating from a stop is when it does this. After putting my foot way down on the gas pedal it will suddenly rev way up and take off. Seems like I need to flex the peddle a couple of times to get it to wake up. After getting it moving there is no stalling or sputtering at all.

Do you guys think this is the MAF sensor? Before I had this problem, I replaced the idle air control valve so I know it's not that. Any recommendations on how to clean the MAF?

what you describe sounds like when I was running with no maf sensor (during some tuning work). Is the SES light on? Any codes?
