High Rpms At Starting

1987 W124 M103 300E
Engines rev to 5000 + RPM at starting, I then shut off the car.
After 2 to 5 attempts it runs fine. Make no differences warm or cold.
Afraid to damage engine.

1-Have replaced Idle air control valve The 2 rubber hoses to the valve. ( Cracks found in the vacuum hoses / Detected from vacuum smoke test.)

2- Replaced OVP relay Car is running much better.

Engines still revs high only at start up, Same Scenario as before mentioned. Need best course of action, Thank you.
