I had the intake off today, and noticed that there is gunk in my TB:



Is this normal? The car has 65K miles on the clock. Should I run some TB cleaner through it, and at the same time MAF cleaner through the sensor?

Also, I looked at my stock airbox and was wondering if this needs replacing:




What is this?

that carbon filter is riveted to the inside of the air box. It is not replaceable.

Firstly that TB gunk is normal, especially if you've never cleaned it through the 65k miles.

I usually clean my TB whenever I'm cleaning out my filter.

I use some WD-40 on a cloth and wipe off the gunk.

Be careful on the MAF as you need to use the right cleaning products so you don't mess up the sensor.

I believe only Isopropyl Alcohol is used for MAF cleaning, I don't know of any other product that can be used to clean the MAF

Haven't used CRC MAF on my 2012 ISF yet but I have been using it for years on my '98 GS400. Works well. I clean both MAF and throttle body with it.

Looks like it'll get the job done since it's specific to MAF sensors.

Have you found anything like this in our region Hamood?

I was going to use CRC TB cleaner for the TB, and CRC MAF for the sensor.. I've been using it for years before, but I never worked on the F.

I don't suppose anyone here also uses the 'Seafoam'? Or is this a dated maintenance task?

They recommend that you clean your MAF every time you change your air filter. I clean my MAF once year, make sure you use quality MAF cleaner they are designed not to damage senor on MAF. I use CRC MAF cleaner, if you haven't cleaned your MAF once you cleaned it you will notice sharper throttle response, you'll feel slight bump in power and better fuel economy

Who is they? The oiled filter manufacturers? Lexus does not recommend cleaning the MAF element unless it is part of troubleshooting a MAF problem. I have never cleaned mine and have no expectation of ever cleaning it because I run the OEM paper filter.

If there is anything on your MAF or in your intake tube, your filter is not filtering and you might as well just run without one.
