This weekend I cleaned my throttle body.
Items you will need: 10mm socket/wrench, rags, flat-head screwdriver,wire,wire cutters, Throttle body cleaner, MAF cleaner,tooth brush.
First step: Remove the negative on your battery. I used the 10mm on this.
Next: Remove the engine cover. There are 2 10mm nuts to remove.
Next: Disconnect both clips on the air cleaner housing.
Remove the air filter. If it is a paper one, replace if needed. If it is the K&N filter like mine. Clean it with the cleaning kit as per directions on the kit.
I use wire to pull the air cleaner housing out of the way. Wrap wire around it & connect it to the base of my antenna. (The black cylinder thing on my antenna is my XM antenna)
Next: Remove 2 bolts holding the MAF box.10mm socket
Then loosen the screw -Either 10mm socket or phillips head screwdriver. I used the socket.
Once the screw is loose, you need to wiggle the housing back & forth, pulling to the left. To remove the housing from the throttle body.
Once removed. I use wire to pull it out of the way. Wrapped around the plastic neck, not the hose.
Then I wrap it around the antenna base.
Everything is out of the way without completely removing.
Cleaning the MAF: I put a spare rag at the backend of the MAF housing.
Then I spray the MAF cleaner into the housing onto the MAF sensor. It hangs down & has a circle on the end. Follow the directions on the can.DO NOT touch the sensor with the cleaner straw! DO NOT touch the MAF sensor with anything. Just spray it with MAF cleaner & only MAF cleaner. The MAF wires are very brittle & can break if touched. If you damage the MAF, it will be several hundred for a new one.
This is the throttle body to be cleaned, inside it.
On to cleaning the throttle body: I lay a rag on the engine below the throttle body to catch any drippings.
Use a flat-head screwdriver to open the butterfly.
Generously spray throttle body cleaner inside, the top & bottom
Using a toothbrush, scrub inside the throttle body as far as you can reach. Spray & scrub. Also use a rag with your fingers or wrapped around the brush to get the gunk out.
When finished, reverse the process to put everything back together.
When you start your truck it may sputter at first, just give it some gas. It is burning off any TB cleaner that may have entered the engine.
If you want to remove the throtlle body to clean it. I will have pics on the next screen below.
Dexdawg found this for cleaning the MAF on an FJ, it looks identical to the Tacoma. Good find!
