How-to clean your AFM

[rmahawaii]

Hello Skyliners, I had searched the entire forum and found no instruction on cleaning the AFM. Can someone please provide a step by step instruction on doing this? Thanks.

1. disconnect your AFM from the pipe that leads to the turbo

2. unbolt the airbox (if its still there) so that the piece conneted to the AFM is loose

the afm and half the airbox should come out together

3. get some break caliper cleaner/ electrical contact cleaner from supercheap auto

4. hold the AFM upright and spray in small bursts into the AFM onto the element which you should be able to see. don't use too much - keep it for next time

5. let it dry (should not be long) and reverse the order you did to take it out to get it back in

your AFM is clean! now all you have to do is reset the ECU and your right as rain!

Thank you for your instruction WazR32GTSt. I had never seem a AFM before. Can you please give me more detail on the location of the AFM and how do I take the AFM out for cleaning? Thanks

[nismoman18]

the afm is right b4 the air box or pod filter if thats what u have. Its a hard plastic tube with an electraical socket connected to a temperature sensor and it wont really need cleaning unless you have got a dirty filter or no filter. Why do you want to clean it though ?

[rmahawaii]

Cause my car will stall while slowing down and people from this forum suggested cleaning the AFM helps.

[WazR32GTSt]

if you have a BOV that vents to the atmosphere then that could also be the problem - it adjusts for the air that is vented back to the intake when the throttle body closes

i'd say a stalling problem is much more than a dirty AFM

[rmahawaii]

Mine is a GTS NA...so no BOV...

i am just trying everything that maybe possible. thanks

MAP sensor?

i cleaned my AFM's on my RB26 smoother, also regapped plugs no misses now.. and revs to 8000+. just need a new AFM plug..

give it a good spray with a decent carby / throttle body cleaner. that stuff disolves grease and dirt like nothin else!

hey guys,

yea this is really good but some pics would be smashin'!

[Johnny Cash]

Yeah, pics would be good.

So if i take out my AFM, spray carby cleaner inside it (where the little

tonsil sticks out in the tube of the AFM), wait a while for it to dry then

put it back together, it should run better???

I already cleaned the AAC, so I'm working my way through the list.

[Johnny Cash]

Electrical cleaner or carby cleaner? which one to use inside the afm???

[Johnny Cash]

Just got confirmation NOT to use electrical cleaner inside AFM. So it will have to be carby cleaner then... wish me luck!

[Johnny Cash]

Can someone PLEASE clarify once-and-for-all which is the best cleaning agent for the inside of an AFM?

- Electric Contact Cleaner

- Brake Cleaner

- Carby Cleaner.

I'm looking to do it TONIGHT, and want to know what to buy.

Thanks,

Adrian.

[WazR32GTSt]

they will all do the job...

brake caliper cleaner and carby cleaner are pretty much the same thing from what i understand...

[Johnny Cash]

Well, I'm being told that carby cleaner will leave a residue, and that will attract dirt to it and clog up the afm sensor again. Whereas the brake cleaner evaporates and doesn't leave any residue.

Either way, I'll use ONE of them, and if it fixes my stalling problem, I'll at least know that's the cause of the problem.

Thanks,

Adrian.

I'm going with an electric contact cleaner from Jaycar (as mentioned earlier in this thread). Will let you all know how it goes in my other post under 'general maintenance'.)

...let the insanity begin...

[flagger]

electrical contact cleaner worked fine for my AFM

[raz0r$harP.UK]

Mate contact cleaner is fine. I've used that one from Jaycar plenty of times with no side effects. Just spray from a distance of about 15cm, in the direction that air flows through the AFM (ie not against it) and you'll be fine.

[Johnny Cash]

Just as well you told me that, cos I wanna go spray it from both sides!

What if i spray it from the wrong side first, then from the right side?

Or should I just not bother, and only do the front side?

Should I stand it up when I spray it, or hold it horizontally?

Thanks all.
