Erratic idle with of without A/C on

[06SubLegTx]

Hello,

 

The car I recently purchased has 96,000 on it.

 

2006 Legacy has a small issue that I have noticed.  When I am pull up to a traffic light the engine rpm's drop down to the point I think it may want to stall. This is more prevalent when the A/C is on, but it still does it a little less when it is off.

 

I have read that the IAC (Idle Control Valve) sometimes get clogged/restricted a little. 

 

Can the EGR also cause this?

 

Thanks for any help

It does not have an idle control. It has a drive by wire throttle body. One of the common problems we see is these getting dirty and not responding the way the computer asks. It is most prevalent with 05/06/07 DBW throttle bodies. You can try cleaning it with induction cleaner but if that doesn't work a new throttle body will be needed. They ain't cheap.

I will try that. It looks like one was done already (the new gasket looks very clean/new.)

 

I will get some throttle body cleaner, and let you all know if it works.

 

Thanks for your help..

unless done in the last coupla years, your car is due for a timing belt system service.

Hello,

 

Yea, I am going to purchase all the parts in a week and do it.

 

Does someone make a special shop tool for the cam seals?

Shop tool for installation? Yes Subaru makes them through Kent Moore. They are about $45 IIRC. Special order. You don't need it though.
