1972 350SL (W107)
Hi there!

I own a 1972 350SL (W107) which used to run beautifully, however I managed to overheat her due to a fluid leak. Luckily, the engine didn't seize and after a few months at the mechanic she was running smoothly again.

Except for one thing: once the engine gets warm it idles very low and cuts out. So whenever I come to a stop, be it in drive, neutral or park (she's an auto), the engine cuts out. Plus it doesn't do this for the first 10 or so minutes of driving.

I tried raising the idling revs, but that didn't help. So I don't know what to try next and thus I have come seeking the infinite wisdom of this forums members.

Any help would be appreciated and if I've left anything important out just ask.
Thanks!
 
An air leak into the manifold.

Try spraying around all joints with plus Gas or butane and see if the revs rise.
