Question Idle problems

Here's one my dealership can't fix. When I first start my engine and the engine is cold it idles from 1500rpm to 1200rpm back and forth about three to four times and then settles down at 1000rpms. The MAF has been changed a week ago it initially fixed it then it started doing it again today.

What year is your truck? Did they discover any diagnostic trouble codes? Have they looked at the Air Control Valve or the idle speed control unit? Interesting condition.

(Just put it in ECU lockout! - not sure what the '64 term is)
