At one time I thought it was dark smoke, but have realized lately that its more whitish gray and stinks like fuel only at idle. I have no oil consumption. No codes. Idle is a little choppy but it runs and cranks fine.

I suspect that maybe I have an injector or two dribbling fuel all the time. My question is would I expect to have warmer temps on that cylinder or colder temps when shooting with a temp gun. I think higher but not sure so I thought I would get your opinions. I did shoot it after driving it and had two warmer than the ones around it and the ones I could get to on the passenger side. I plan to compare it to my good truck tomorrow but thought I would see how y'all saw it.
