I was wondering if anyone had any insight/suggestions for cleaning the throttle body of a 2005 Outback XT? It looks like I need to remove the intercooler.

I have some oil residue on the intercooler entrance and I expect that must be leaving some residue down in there. Figured it made sense to clean it. Maybe not? Just leave well enough alone?

The idle is smooth cold since I replaced the timing belt, but feels a little rough when warm. I was going to clean the MAF and throttle body but realized that I really couldn't do it that easily!

I realized that I should also see if the rough idle is only in D (5EAT), as that might point to something else... let me check that...

You could hook up a bottle of Sea Foam to an air inlet port prior to the intercooler and let the engine suck it in. Passing through the intercooler it will loosen some of the carbon.

Or you can remove the intercooler, clean it and the throttle body and put it all back.

An engine that breathes performs better.
