When I start my car and its cold out, there is a miss in the idle around 1300, and I can hear a vacuum leak when controlling the throttle under the hood. I disconnect the tube going to the top of the EGR valve and the rough idle stops. This only happens when the engine is cold, so I really don't know what exactly to think of this. Once the engine is warm, the rough idle around that approximate RPM disappears. :shrug:
