Strange idle
So I drove my car for the first time this year yesterday (02 A4), and everything ran great, nice and smooth on the freeway. Got to my destination and let the car idle for a minute or two and I got this weird rhythmic side to side kind of movement. Don't suspect torque tube cause it was in park and idling. Maybe an engine mount going bad? Any ideas out there?
Thanks!!!

Hard to say. Any check engine light? Check the codes anyway in the DIC. Could be old fuel since it sat for a while, could be maf, could be 02's, could be spark plugs...the list goes on and on. Hard to pin point, would need more info to help point in a direction

Hey Doc, thanks for the reply. I have no codes or CEL, the MAF was cleaned with CRC MAF cleaner over this past winter and the plugs are about 1.5 yrs old. Could possible be some old fuel but it ran perfectly smooth at freeway speeds for about 50 miles. It needs gas now so maybe it will clean its act up with a full tank of fresh fuel
