For all of you who have gotten carb cleaner on afm

[stolensupra]

I posted about a week ago about an afm that had gotten carb cleaner in it. I was showing code 31 i believe and couldn't rev over 2500 or idle right. After doing some research on other car sites about this problem I decided to try one of the theories. I ended up q tipping small amounts of lacquer thinner (or equivalent residue free solvent) then pulling the cotton on the q tip into a cylinder and twisting it into the air holes to get the gunk out, then re rinsing with lacquer thinner, then blowing compressed air through both holes. I repeated this about 6 or 7 times, then let the afm dry. VIOLA! saved myself up to $750 on new AFM (although i did buy another afm from bis_1315m who's a great guy to do biz with) I wouldn't do this to any electronic unless it is a complete last resort and your afm is fucked anyway. I hope this is helpful to those of you like me that sprayed carb cleaner irresponsibly.

Well that is nice to know. But as long as you have a good air filter(not k&n or hks) and you do not try to clean it it should be fine unless it craps out.

I ultrasonically clean them in Freon 113. The stuff is hard to come by though. You're lucky whatever was in that particular brand of carb cleaner didn't craze the optics...

Mine took a little while to die after cleaning. Hopefully you wont have the same results, But mine would freak out in rainy weather. Up untill one day i got nothing from it.

WOAH! can you elaborate on this? mine was fucking up hard core today and its raining like a cow pissing off a flat rock. so many check engine lights (code 31) and stalling all the time...

It would run shitty, stumbling. Only when it rained though. I dont recall if i was getting any CEL's but it was defiantly only when it was rainy or very high humidity.

My guess is i did minor damage to the foil inside the electronics with the cleaner. When it was rainy moisture would combine with the other damage it would struggle to read the movement of the foil that gauges air speed.

At the end of that summer it had become inoperative. On my MAFT gen2 i was running at the time i would get 0hz input, And making the switch to the GM 3inch MAF solved the problem. Ever since i never looked back at the stock AFM problems. Now im standalone and speed density.

thats odd mine does the same exact thing.

If you get to the point of having to buy another AFM, you should just go MaftPro or something else that ditches the toyota AFM altogether. If you gotta spend money, spend a bit more and make it an upgrade.
