- Locking pliers or flathead screwdriver (depending on your clamp style)
- Torx bit (size?) for TPS & IAC
- Socket (10mm?)
- Throttle/carb cleaner
- Toothbrush (optional)
Use some throttlebody or carburetor cleaner (other cleaners may work, also, but these are made specifically for this task…), and a rag.
Spray and wipe, rinse and repeat. That’s all there is to it.
Notice the nice, shiny throttleplate. That’s the side that faces the plastic intake tube… (this is before any cleaning)
Now look at the backside… it’s hard to even tell where the throttleplate is, but it really is that black circle.
Clean that puppy up! You don’t have to get it uber-clean, but there’s metal behind that gunk somewhere – find it!
While you’re at it, clean up the IAT valve. Go ahead & use the same cleaner to get any major gunk off the tip, spring, and gasket.
Installation is the reverse of removal.
