MAF Sensor cleaning
 

My FR-S is nearing 60k and the idle is a little rough at times. Decided it's time to clean the MAF sensor and reset the ECU. Picked up this stuff (there's really only a couple different brands that offer MAF cleaner). Has anyone else done this with any positive results? Thanks

do it)

If you use 4 cans you could get another 40 horse power!

I'd never done it in 11 years, so I figured I'd try it.

Made no difference.

Saw some people also get a throttle body cleaner ... I intend on doing. ... When I'm not feeling like a lazy mut.

It can only help if the MAF sensor really was dirty. The only reason I can think would be from oil coming off of one of those reusable elements.

Have you changed your spark plugs? iirc, they're due to a change at 60k. Unless you are using an overly oiled air filter, my guess is your idle hiccups are from the plugs.

My gut says MAF before plugs. I'd check LTFT at idle before cleaning MAF and also would watch STFT immediately afterward. @tomm.brz, amirite?

I use CRC MAF Cleaner. I don't have any specific issues, and haven't run into any issues (with the car or the product). Just part of regular maintenance every other oil change since I have an oiled filter


130k miles on ODO. Spark plugs every 60k miles, got "new" old coil packs at 120k

no real need to look at stft unless it is like pegged hard to either too negative or too positive values.. in that case it will shortly transfer it to ltft anyway
Cleaning a maf is never a bad idea, specialy if you have the specific cleaner that is safe to use on it

Just spray the element. Do not touch it.
I’ve always run oiled K&N drop-in filters since 1988 and periodic (annual) sensor cleansing has been part of my maintenance routine.
:burnrubber:

I need to clean the MAF sensor at least once per season with using an HKS mushroom intake. At some point it has sucked in some oil and it took me a while to discover that a dirty MAF was THE reason my car wasn't running as it should. It is best to remove the intake section with the sensor and spray it really good outdoors in a well ventilated area.

Coil packs are a big one, the front passenger one tends to go out because its so close to the header.

I also found my car to be smoother with a newer battery .. but that was when the batteries were on their last leg (+5 years of use)

I haven't yet. I know they are due at 60k but some say they should be good for 120k. Thanks!

Its called High flow performance air filter. Worth the extra 3HP. I would rather replace pcv than touch any electrical stuff
