Carb cleaner works well, although I've used a chunk of T-shirt I spit on to get me through a trip Intake plenum is where the air intake hose meets the top of the engine. IAC/Stepper is underneath the breather hose, on the front (headlight) side of the engine. Its shape and what holds it in depends on the vehicle make and year.
