Hello all,
I drive a 1986 BMW 325es. It hasn't given me any problems for about 10,000 miles until just the other day. I started the car up and my RPMs kept climbing until they were at about 2500. If I drive the car around, the idle speed will increase to about 3000. I'm fairly certain it's a vacuum leak, but I have no idea how to diagnose where the leak is. I have already cleaned my TPS and ICV, and I don't think they're the root of the problem. If anyone has any advice, please help.
