How to Clean MASS AIR FLOW Sensor to Stop Car Hesitation Nissan 350z 💥 INFINITI G35

[@enochbos1on]

Today, I just bought a used '09 G37x sedan AT w/manual mode. Drove it home 60 miles, highway, city and back-roads. No problems at all. Car seems(ed) to be running like a champ and in great shape for the year and mileage '09 135k. Stopped at the store, turned off the car etc, apx 30 minutes before I began driving home, came to a stop sign and upon accelerating from the stop, the car jerked and stuttered, power dropped way down. Pulled into gas station immediately, freaking out, parked it, gave it some gas to rev it and the engine would seem to wobble and shake the car all while not getting the revs up due to lack of power. I had to get the car home as I didn't even have the new plate on yet. So, what I ended up having to do for the last 4-5 miles home, was that I found that by shifting into manual/sport mode, matching the revs as best as I could to get up to 5th or 6th gear, then I could get up to the speed limit and while still low on power, the car ran smoothly. Came to more stop signs and red lights etc, every time I tried to accelerate in auto, there was just no power and the transmission didn't seem to want to shift up unless I quickly switched to manual mode and got it up to a higher gear. Even in 5th, 6th or 7th gear the power was very limited as well. Got home. Parked it. Saturday night ruined. Nobody to look at until Monday. I did however speak to the dealership before they closed and one thing they mentioned was that perhaps during the pre-sale detailing, done just before I left the lot, as they power washed/sprayed the hood, maybe a sensor or something got wet and is causing failure or limp mode or something like that. I don't know, maybe. I've been reading about and watching videos about dirty mass af sensors, dirty throttle bodies and re-setting the ecu. Hopefully the issue is that simple and all is well. If not, thank God I got a warranty lol. Always something. Anyone experience something similar?

[@YearVeteran]

Be very cautious and careful!.. In my case I actually disconnected my throttle body and removed it because I wanted to get a better cleaning. Little did I know that disconnecting it would cause a big problem. Not to mention there's a ring of some sort that sits the entire circumference right where the butterfly sits. Despite what they say I wouldn't mess with the butterfly either! Currently I'm receiving the high idle code and the complete relearning procedure doesn't work! I've read that I will have to take my car to the dealer to have the ECU read by some special equipment they have. I might have to by a new throttle body as well.

[@jhernandez2199]

Robert Canales did the exact same thing a couple weeks ago while installing some go fast parts...had the whole plenum off with tb attached. Cleaned it up real nice put everything back on and got idle speed something code (high idle). Tried to do idle relearn, disconnect battery etc but no luck. Then the other day while racing my buddies maxima it had apparently turned off it was weird.

[@rizocars6115]

Robert Canales bro I have a q50 and I did the same thing to install this golden tape he has in the video, I cleaned them very well but nothing worked, now the car is shaking like crazy, what car you have and how much you had to pay for that

[@MotordyneG35]

The idle relearn 9:08 works. I've disconnected the throttle body a couple of times, touched the butterfly and even upgrade to a bigger 75mm throttle body. Each time you disconnect the throttle body harness or touch the butterfly, the idle will be messed up. Once you properly complete the idle relearn 9:08 will it correct itself. Disconnecting the battery will do nothing. It's been a couple of months now. What did you find out was the actual problem?

Will it go into limp mode because of a dirty MAF sensor?

[@MrHollywood663]

Motordyne G35, I have a 2008 g35 infinity and got a p0171 code. Is it true that if I disconnect the MAF sensor and car stays running means that the MAF sensor is no good??? It's a dual MAF sensor system, do I disconnect both or the one side that I believe is bad if this trick really works??? Also I'd like to get your opinion on the hydrogen oxygen carbon cleaning machine to clean carbon from engine. Do you believe that this is a waste of money or does it work to clean carbon??? Thanks. By the way I did your idle relearn after cleaning my TB and it worked like a charm for me Thanks for this great video.

I have a question abt aftermarket intake. I had 2013 G37 with Gen 3 Long tube intake from Stillen, i had a check engine light on, the code read as if they were from Air Flow A and B. If cleaning MAF would clear the Check engine light on? I used to send it to the shop where i installed it. They didnt see any wrong with it. They just clean MAF and some filter in the front and reset. Its been abt 6 Months and the check engine light came back. Whenever the that light is on, sometime the car is not respond to the acceleration and i have to turn the car off and wait for a few second to turn it back on to drive like normal. Do you have any idea on this problem? Thank.

[@rj5279]

I have a 2003 G35 Coupe and recently did my valve covers and cleaned my throttle body. I was getting the high idle and did the re-learn process. It does drop the idle to the proper rpm, however whenever I shut off the car, it resets back to a high idle. Ive done the ECU reset as well as the other procedures named before the throttle body reset. Any experience with this?

No, the idle relearn always works for me. Any check engine lights? You may a have a small vacuum leak somewhere.

[@kc_gteam1336]

So the other day I installed a new MAF sensor because I was getting a p0102 code. The new senor fixed that problem that I was having but now I've realized a few things. First is I feel like the car is slower when accelerating now for some reason and the second thing is that when I first start my car up, it idles fine for a few seconds and then jumps up and back down like I revved the car even tho I didn't touch the pedal. Any ideas?

[@beanz2092]

KC_Gteam have you fixed this issue? I got the same code pop up recently

[@kc_gteam1336]

@@beanz2092 Yeah I did. My MAF sensor was causing the problem of the code and doing an ecu reset and a idle relearn fixed the slow acceleration and weird idle.

[@icecubez130]

Can you clean the throttle body without unplugging it? like spraying the outer area and gently wiping without touching the butterfly valve and letting it dry long enough before putting the intake tube back on. I had to do a throttle/idle/ecu relearn before and it was a pain (you make it look easy). But I really want to clean the MAF and throttle cause i'm getting crap city fuel economy.

[@MotordyneG35]

Yes, no need to unplug it and you can do it that way. But, to fully clean it you need to push the butterfly valve open. Seriously, try the idle relearn right now. If you start my video when I have stopclock out while in your car, it is so easy. You really can't mess up and then once you feel comfortable doing the idle relearn procedure, clean the throttle body.

Only if you touch the butterfly in the throttle body do you have to do the idle relearn. No, just clean it and drive.

[@shinjiikari5947]

@@MotordyneG35 thanks a lot 😁

[@RainAion]

Probably a long shot, but do you know off hand if this procedure is more or less the same, or similar, for most cars? I'm not the greatest with cars but I've been trying to fix an idol issue with my Mitsubishi Galant for the last year or so. Mitsubishi dealership tried telling me my best option was to pay $3,000 for a replacement used engine (lol), or pay $500 for them to open the engine block, and that doesn't include anything else after its open. Such as a cracked piston which they'd charge $1500 for (lol again). If you don't know, It's all good. Sort of sucks that Mitsubishi Galants/Lancers don't have a big community unless its a Ralliart or an Evo.

[@MotordyneG35]

Cleaning the MAF is basically a universal procedure for all cars, the only difference is the configuration of the air intake boxes that hold the MAF's and how to get to the MAF's will be different. The principal is all the same. How many miles are on your Galant? You can defiantly try this and see if it works, it will not hurt it that is for sure. What has me concerned is if a shop is telling you that a new engine is what you need, I think you have bigger problems than a dirty MAF, unless that is 1 shady shop! Is the engine making knocking noises? Are you overheating? Or is it just a rough idle issue?

[@RainAion]

The Galant has 105,000 miles on it. And yeah It's only an idle issue. When driving its fine, when idling at a stop light or a stop sign or just sitting in park it starts shaking. It only starts doing that when its under 1,000 RPMs, above that its fine. If I put it in neutral, it stabilizes a little bit, but it still does it. Changed the spark plugs, changed the o2 sensors, changed the third ignition coil and nothing. I don't remember the code on the service engine light off the top of my head but it was a coil 3 misfire, hence why I changed that ignition coil. The place I took it to for them to look at it was an actual Mitsubishi dealership lmao. I was a little annoyed that them of all people couldn't figure it out. Edit: One of my other thoughts was the idol air control valve but I haven't looked into that yet, I don't even know where that is on my car at the moment. No over heating and no knocking noises.

With the Admin intake, would the larger diameter around the MAF sensor cause bad readings and require a tune to compensate?

That is correct. You have to get a tune with the Admin Intake. Without a tune, trying to run the intake the car will idle and run badly.
