Hi, I bought myself a 1991 300TE-24 Auto estate a few weeks ago. I'm very pleased with it, but there are a few issues that need looking at, one of which is the idle after a cold start.

When started from cold, it will start quickly but cannot idle on its own; I have to keep blipping the throttle or the revs fall and the car will stall itself, there is also a smell of petrol from the exhaust when it is started from cold. After a few minutes the car idles fine and the petrol smell goes away.

Also, when I try to start it warm, it takes a few seconds to start. The starter motor turns normally but it just takes longer to fire, though once started it idles smoothly and runs fine.

Can anyone help?
Thanks.
