The vehicle should idle at a higher speed until it reaches operating temp, especially in cold weather. Check your idle on cold mornings. My 2010 idles about 500 RPM's higher until it warms up.
Gasoline vaporizes easier in warm weather than in cold. To compensate, the idle increases to deliver more gas during cold weather startup. If the idle settles back to normal after warm- up, there is nothing wrong.
When it gets cold outside my truck will start but won’t stay running unless I keep a foot on the gas. If I let off it dies.

Ok here it is; just put new sending units in an 89 f150 5 liter with dual tanks. Ran freaking great before I put the units in. Now no matter which tank is selected it dies out after a few minutes...

My Ford F150 has been running fine but today I crank it and it won't stay running. The check engine light does not come on. Anyone have any ideas in what it could be?
