I recently posted a thread with a lot of great feedback, I'm finally taking in my car to get it checked by a subaru dealer. The symptoms are a very high idle when the engine is first started(1.5), as it warms up the idle becomes very rough (tach needle jumps up and down from .1 to 1.5). The engine shakes when im at a stop, and often stalls at lights, but it always starts right back up. Also, When i try to moderately accelerate, not flooring it or anything, the engine doesn't respond, after 5 sec it all of a sudden takes off. The check engine light has never come on during any of this, but from my earlier post i think i have narrowed it down to either the maf, cleaning the throttle body and iac, spark plugs, and check for vacum leaks, is there anything else that could be wrong with it? im taking it in thursday morning so any more ideas would really help, thanks
