1993, 500sl, idle when hot

[john masters]

Help please Im new to this.
My 500sl when hot has an eratic very fast tick over, uneven running, loss of power and the mpg gauge shows economy I can only dream of any ideas please.

 

[spanner]

Sounds like you have a vacuum leak.

 

[BlackC55]

Or a horrendus missfire.

How new are the dizzy caps?

 

[lynall]

I reckon spanners hit the nail on the head there
