Surging idle when warm.

1987 190 2.3 16v 178,000 miles

Starts up fine when cold and warm. Idles perfect at 950 when cold. Then as the temp gets up to 70ish the idle starts to hunt between 700 and 1300.

Could a leaking cold start injector cause this surging?

Is a cold start injector a common failure?

Thanks,

Christian
