Throttle Body Cleaning
This weeking I want to clean my cars throttle body. It has about 35,000 miles on it. This my first time cleaning the throttle body, how do I go about doing this. What kind of cleaner do I use. What are the benefits besides better mpg, thanks.

Get a can of teflon safe throttle cleaner from Advanced or Autozone. Make sure that it is not carb cleaner, because carb cleaner is not teflon safe.
I use Remoil + Teflon gun lube on the spring and on the throttle rail.

Just make sure you remember how to put the intake back together when you're done.
First time I did a cleaning, I forgot to plug a sensor back in and ooo did the engine sound bad..
I think www.motorvate.ca has a write up on the procedure.

This is a can of TB cleaner from a fuel injestion kit I had laying around in my tool box. As mentioned any TB cleaner will do

This is a pic of the TB before the cleaning. Notice a black carbon ring around the plate

After the TB cleaning, ring is gone

Definately one of the easiest maintenance you can do to your engine. I used a old tooth brush with the TB cleaners.

NO. That would not be wise. You need to disconnect a few sensors to remove the intake in order to get to the TB.

Bottom line, disconnect all tubing leading towards the TB, open the throttle plates, spray, brush with toothbrush, spray some more, brush some more until you're satisfied it's clean. If you're concern you probably sprayed too much into the motor remove all the spark plugs and crank the motor over for a few seconds.
BTW: Seafoam by itself will not clean the TB. Seafoam is ingested into the motor after the TB.

If you have over 75k-100k miles on the car and have never cleaned the TB, it would be best to go stop by the dealer first to pick up an extra gasket for between the TB and the Intake manifold. It's about $5.
Now you can completely remove the TB from the intake and clean it from the other side as well.
Removing the TB from the intake manifold will more than likely cause the old gasket to break or fall apart. This is why you need the new one.![Smilie](https://maxima.org/forums/images/smilies/smile.gif)
Only 4 bolts holding the TB on.
I did this last year and man was there a THICK layer of carbon on the other side of that butterfly valve.
It also lets you clean deeper into the intake manifold.
