'84 Euro 3.2 running rough after start
 
Helping a friend troubleshoot his '84, 3.2 Euro. Starts fine. A few mins after starting the motor starts to hunt with the revs at idle varying from ~1000-1200 rpm. Mildy rough acceleration. Goes away after 15-20 mins when the engine is up to operating temps. Car has <50K miles. Cold start valve? TIA

What year car?
Most 3.2s have motrinic fuel injection and warm idle should be 800-1000 rpm depending on year and program. No cold start vslve.

1984. Added it to the body of my question. Thx. I have an '83, hence my "cold start valve" assumption.

Check vacuum leaks and clean Idle Control Valve First.
