Couple weeks ago i changed out the radiator. Now in the morning when i start my car. It idels high around 2200 rpms and then boggs down to where is sounds like it wants to die. Then repeats the same thing over and over. Its boggs when driving cold, have to rev up higher so it actually goes. But when is at normal driving temp. It drives like normal. Any ideas?????

Sounds like a dirty IACV (idle air control valve), but I wouldn't check that first. Clean your MAF sensor first, and if that doesn't do the trick, take out the IACV and clean it up. It may be full of gunk.

So it dosent sound like anything weird which is good. Where is that IACV located?

This is certainly one of those things to try yourself. The dealership RAPES you on this service (experience

).

**Me-Yellow-Bug-I** · 04-09-2009 11:48 AM

Thats why i thought to ask here first. See if it was something some what straight forward!!! Dealerships are full of subie rapers

Definitely. The dealership would probably charge hundreds of dollars just to clean it. It only takes about 30 minutes to do it yourself if you know what you're doing.

Pick up some carb cleaner and q-tips.

Heh, my local preferred mechanic charged me $20 to clean the IACV when he did my clutch job.

Anyway, if the IACV is, in fact dirty, you clean it, and in the next few months/year, it gets dirty again, clean the PCV system. It'll also help if your air filter or IC gets a bunch of oil on it/in it.

Man that is cheap. I hope he replaced the gasket.

He did.

When I had my LGT, he replaced 4 of the 5 front seals on the motor... Right after, the 5th seal blew, and he replaced that last seal free of charge. He's a good dude, the local Subaru dealership referrs customers to him all the time.
