after tune up, new ypipe, pcv, bugeye startet to run sluggish, gas shut off feel, hesitation on incline or acceleration on 5th gear and boost creep. I did everything possible, from re checking hose, plugs you name it. even mechanic suggest new fuel pump and injectors then a tune(though that's my next step) but low on funds. was getting 20mpg hwy! after reading up on http://forums.nasioc.com/forums/showthread.php?t=1060871 it solved the problem! $8 at napa! runs smooth with no more boost creep or having to ease of throttle for psi to go down! we should have a thread on MAF Cleaning, saves hundreds of $.
There is a myth out there it's easy to do it the wrong way, is this fact or fiction? I see MAF cleaner on the shelf at o'reileys I've just been afraid to make it worse off then it was before.
Its easy. Unscrew, look at the metal parts on the sensor. They will be black. Spray... let dry (10-20 seconds). Still black, spray again. Once clean, put it back on the car. It shouldn't take more then 5 mins total.
make sure you spray not only the intake temp sensor but the acutal maf sensor wires, its a tiny wire on the inside.
yep I read up that the amber bulb was just the intake sensor and the MAF sensor is actually up in the housing near the connection, so I sprayed up in there in the upright position so it could drain out as i sprayed. CRC MAF cleaner for the win.
I cleaned the MAF on my saabaru (probably the first time in the cars life), reset the ECU, and after it learned what fresh air was again, its running great!
same here, never clean it since i bought it in 05, and don't think the previous owner ever clean it since 02! that MAF is expensive! $200+ so gotta be gentle
There is no scrubbing involved. It would be pretty hard to break it. Just two screws and unclip the sensor. Spray and put back in the car. The MAF Cleaner is like $7 and I have yet to buy a 2nd can. Mine is cleaned every oil change.
^^Jux reminding those who haven't done it yet, since i read up on some people actually thinking that the amber color bulb is grease and try to take that off, and not knowing that that's actually the intake sensor, and the MAF sensor itself is inside the housing near the plug. And i read up that people actually opened the MAF sensor up to clean it! risky
I found out that Walser Subaru does this at the 30k services, at least that should help people get it done at all what else falls in this category? I'm thinking brake line replacement, clutch fluid, ??
No pic of it, but I just remember seeing it on my MAF when I cleaned it last year. The spray didn't get rid of it. It was hard and crusty
Is it hanging off the wires or on/around the plastic housing? I have seen corrosion from the grounding inserts as seen in the attached picture.
