MAF and Throttle body cleaning

Postby dawgn86 » Tue Jul 03, 2018 3:43 pm

was thinking about cleaning my MAF and Throttle body this weekend. Have the CRC cleaners for both.

The MAF looks simple enough to take off intact in the air filter tube, clean and replace.

The TB looks easy enough as well, but I keep reading where you will have to perform idle air relearns, etc afterwards. Should I just leave this one alone?

2006 V6 with 175k on the miles.

Thanks

If you don't think you are capable of doing an idle air volume relearn, then you should probably leave it alone.

I probably could if the directions / videos found online are pretty accurate.

I ended up going to the dealership after trying for three days. This one seems like a tough pedal dance. Works for some, doesn't for others.

FWIW I noticed no difference after cleaning the throttle body or anything else in there once Nissan did the reprogram. Less than my instake manifold spacer, less than new spark plugs, less than a new engine driven fan, etc.

Are cleaning the MAF sensor safe?

From my Mitsubishi Eclipse forum days, cleaning the MAF sensor is a no no.

It is if you do it carefully and use either MAS cleaner or electronic parts cleaner. You just want to spray lightly the hotwire, not blast it!

Will cleaning the TB help fuel mileage at all?

I am getting absolutely dismal mileage - like 280miles a tank at most.

Theoretically mpg can be improved but it..
But driving location is the biggest determinant IMO

I just recently got to the 270-280 mark on my 2011 V6 4x4 and I'm ecstatic. I ended up doing the following to get there.

1. SeaFoam via brake booster line. It threw a code about the engine misfiring. After the can was gone, I cleared the code with a scanner I have and it never came back.

2. Berrymans B12 in the gas tank and then filled up. Used the full can.

3. Used a can of SeaFoam spray on the throttle body. Didn't move it, just sprayed it while the truck was on. Took a few tries to get the engine to stay on with the air box off and everything disconnected. It actually removed some of the black stuff around the rim of the butterfly (if that's what it's called) so that more air could go through at idle.

I went from about 240-250 mpg to 270-280 depending on how long I drive on it when the truck is screaming at me 'Low Fuel' :)

Haven't changed the plugs either which I'll do eventually.

With that said, some may say the above is snake oil, but it worked for me.

I decided to tackle the throttle body yesterday and did so without any issues.

I disconnected the negative battery cable and took the throttle body off my PF and to the work bench for cleaning with Throttle body cleaner, being sure to hold the motor side up and mainly spraying the rag and wiping it clean. I did open the butterfly up slowly to get the surface area cleaned.

back together and fire it up..idled high for about 30 seconds and gradually worked back down to normal.
