Hey Folks,
This is technically on a 2008 Impreza 2.5i Manual Trans with 39,000 miles on it. I've asked over at nasioc as well but haven't heard much so I thought I would ask here :biggrin:
After the car has warmed up, when I push in the clutch and brake to slow down to a stop, the RPM's will occasionally dip really low (i'd say 400 at the lowest) to the point where the car sometimes stutters a bit, then it immediately jumps back to where it should. It doesn't happen every time, and I haven't had it happen when the engine is cold (blue light on).
I cleaned out the throttle body (didn't remove it) but it didn't seem to help. The spark plugs are about 9k over and I have plans to replace them in the next couple of days, but I don't think they would cause the RPM drop (please correct me if i'm wrong). I've also had the alternator tested at two different places and it came back normal. I thought about swapping the MAF sensor out of my 2012 forester, but the part numbers are slightly different so I don't think that will work.
Does anyone have any ideas of what this could be? I haven't had ANY check engine lights so i'm having issues narrowing this down. Any help would be greatly appreciated!!
