I noticed when hunting in colder then normal Temp (32*) that my truck runs rough for a few seconds and smokes. It blows blue smoke them white/gray. Is this normal? Could I have a air leak?

 

With my injectors, its normal for a haze when cold. I'm not sure about stock injectors, as I only had those in for about two months, and that was in the summer time.

 

mine has always been grumpy when its below forty, just have to give it a minute or so. not saying its right, but going on five years now and always the same every morning. i wouldn't loose any sleep over it.

 

It will be interesting to see how it acts whe it gets down in the 20's around here.

 

A little smoke on a cold start-up is normal. Mine would haze my neighborhood w/white smoke and you'd have to floor it to clear it out. New supply/return fuel lines, starts right up, little smoke. (neighbors approve!)

 

If you can't plug in when cold smoke is normal.
I had nowhere to plug in at -20°F once.
I was very embarrassed, reduced the viability in a five acre area including a major hiway to about five feet.
