I just had my 95,000 mile 2010 Forester in for the "big job", Head Gasket, Piston Rings, Timing Belt, Tensioner and idler pulleys, Water Pump, Oil Seals, New AC Compressor, Belts, Plugs and wires, filters, etc. I noticed that when the AC compressor cycles off, the engine idle drops very low to the point that it sounds like it wants to stall. Is it possible that the new rings are causing extra friction and the "lugging" will go away as the new piston rings wear in? Or is there some adjustment for the idle that may not have been set correctly?

In neutral, my 2007 5MT always sounded like it was going to stall, to the point where the RPM was so low it was almost like making the car vibrate. Even mechanics (no Subaru experience) who got in my car said there was something wrong because it was going to stall. But I had that car 11 years and it never stalled.

Thanks everyone, I'll watch it and if it still seems like it isn't right after a while, I'll run the "relearn" procedure.
