erratic rpms on cold start
I recently bought a 2001 WS6, 6mt, with 45k. This morning it would not stay idling. I had to feather the gas to keep the rpms up. If I let off the gas the engine would die. There are no check engine lights on. I live about 5 minutes from a highway and I had to feather the gas when ever i would start to slow down. I drive about 10 minutes on the highway and another 4 minutes to work.I had to feather it the whenever I had to slow down. Same thing on start up on my way home.
When I exited the highway I took it out of gear and coasted up an offramp, rpms dropped to 500 until I came to a complete stop then went up to ~700.
I'm completely new to these cars, seems like it could be a vacuum leak? The car is stock with the exception of muffler delete.
TIA
