Runs rough and stalls at times

[sparky57]

Two issues: Starts up ok after sitting overnight then runs rough. After about 10 mins it then smooths out and runs normal. Seems to do it when temp around 32 degrees at night. No engine codes. 2nd issue: after running at normal opertaing temperature when I approach a stop/red light I hear a loud whining noise from engine compartment and when I do stop the engine will either stall or almost stall and the noise is gone. No engine codes. I brought the vehicle today to Fall River Ford in Mass. and they just called me that they can't find any problems and no codes. They're keeping the vehicle all day and I suggest to drive it for awhile to see if at least the whining noise appears. They're going to call me later. Any suggestions?

Fall River Ford just called me back to state still can't find any problem. They suggest to bring the truck in when it does this. I'll have to plan my commute home to drive there instead and hope it happens! As seen in other posts I mentioned the IAC and they stated the TSB mentions a hooting noise like a fog horn. It doesn't sound like hoot to me instead it's a continous loud higher pitch continous noise that stops when either it stalls or almost stalls.
