In late 2015 at 161,735 miles the idle air control valve on my 2002 Toyota Sienna was acting up. So I opted for the cleaning rather than replacement.
That lasted for 4 years 9 months or 44,617 miles before it started acting up again this May. So in May of 2020, at 208,226 miles, I had a cleaned again.
THIS time it only lasted 7 months and 4k miles. So today I just said screw it and replaced it with a new one.
But when I looked inside the port of the old one, on the side that bolts onto the air intake, there was a LOT of carbon buildup. And when I took the end of a screwdriver and flaked a piece off, though small, it was about as thick as a fingernail.
So my concern is that there might be something else going on with my engine that it's spewing (for lack of a better way to put it) that much carbon into the IAC over a short period of time and as a result the new one may not last all that long.
Any ideas?
