Step 1)
Remove the
stock intake system (Airbox Lid - Throttlebody)
Step 2)
Remove throttlebody
Step 3)
Remove
TPS and IAC from throttlebody
Step 4) 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.
Before:
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.
Assembly is the reverse of
disassembly.
