IAC location on a V6 ?

Trying to locate the IAC on a 92 V6 Camry for cleaning. The engine has that maddening stumbling problem when cold and I guess I should start with IAC!

What is an IAC?

The V6 IAC for the 3VFZE is totally different to the 4 cyl version. If you look towards the TB, it is that 2" cylindrical thing hanging off the right side behind the TBS. To remove it, you need to disconnect the wiring harness and pull some vac. lines and 1 or 2 coolant lines from it and two bolts. If you want to pull it, be sure to get a replacement gasket for it first. You may be able to clean it ok if you just remove the air intake hose and open the throttle plate with one hand and spray into the IAC opening on the right with the engine running. (IAC must be open).

Your problem however may be related to a few cracks in the 4 " dia rubber air intake hose. These tend to get brittle on these earlier V6 camrys at high mileage and develop holes in the crevices which throws off the whole air-fuel mixture, especially in open loop operation when cold starting. They can be hard to see unless you take it right off or pull and stretch it a lot while it is still attached.

I also just want to add that you can wrap some decent wide plumber's plastic tape (heavy gauge) from your hardware store carefully around the around any bad spots in the intake hose (clean the hose first with soap/water or alcohol) to fix it temporarily for a few weeks and then order a new hose online (
