Air control valve

Featured Replies

When i start the car cold, it sometimes runs very rough and the rpm start to descend and finally it stalls and it shows a CEL light. I checked the code and it was a Error code.24, which is the air control valve.

 

Is it the same as the idle air control valve or is there a another air control valve on the engine that i don´t know about? The car is ´91 Legacy 2,2.

The IAC valve is very expensive. I cleaned it last summer and the car idled smoother for some time.

Last thing i want to do is to buy a new one because i´m a student!;)

What can i do to make it last longer, cleaning it or some adjustments?

No adjustments, but I do remember a thread posted a short while ago for cleaning the air control valve. If yours is an automatic transmission car, I have a good working used one available (check my post in the for sale section).

I´ll probably get a used IAC valve soon at a parts sale. But does a IAC from 1.8 or 2.0 subaru engine fit to a 2.2? Are they the same or is there some difference?
