How to clean your throttle body -DIY

This is a DIY - completed surgery today

Flat head screw driver, pliers/ needle nose, socket with hex, carb cleaner, toothbrush


optional to remove the air box - I didn’t

SURGERY

To remove tube that connects to throttle body, and air box — Loosen 4 clamps: air box, throttle body, vacuum tube in front, clamp at bottom

slide out vacuum tube complete, then reach down and slide out bottom tube. A bit of wiggling to remove tube from throttle body and air box

2-3 minutes later

unplug harness from throttle body.
Two vacuum lines at bottom of throttle body with clamp. Mark them to not cross when reversing surgery.

hex with socket, remove the 4 bolts from throttle body. One of the screws hold a bracket to plug up a harness

remove throttle body (2 minutes later)

AT NO TIME SHOULD YOU ATTEMPT TO MOVE THE BUTTERFLY ON THROTTLE BODY…. NOT YET AT LEAST

spray inside and out of throttle body while using toothbrush to scrub away all the buildup. Use bristle to your advantage while cleaning. Once you are satisfied then

SLIGHTLY PUSH ON BUTTERFLY ENOUGH FOR A HAIR TO GO UNDER BUTTERFLY, while using your toothbrush. —— gently holding butterfly

HOLD UP complete TB to light and you should see space 🤣🤣

spray and clean, spray and clean….

use a cloth to wipe the tunnel where the TB bolts into. Careful not to disturb the gasket, and mesh.

Night and day difference.

sorry no pix, but the GUNK buildup was surprisingly a lot.

REVERSE SURGERY

DISCLAIMER: I did the above and no problem.
on start up, the idle was at 1,100, then steady dropped to 700 🤛🏿🤛🏿

drive car around block…, nice!!!!!

TOTAL SURGERY TIME: -30 minutes

Appreciate you taking the time to post that. I'm sure that TB should be routine maintenance when plugs are changed or valve cover work is needed.. About what mileage would you recommend this be performed?

My recommendations is at 60k to 100k intervals, and depending on how you maintain vehicle - - oil changes, spark plugs, gas, air filter etc

if in doubt, remove tube and peep into TB. Use a tooth pick to scrape away then gauge. Inside TB was far worse than outside
