January 25, 200620 yr 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.
January 26, 200620 yr Author 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?
January 26, 200620 yr 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). 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!

February 11, 200620 yr Author 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?
