Flutter and white/blue smoke that smells like diesel

My truck has a slight flutter when you first hit the pedal and then there is a little blue/white smoke that puffs out abs then clears up. New injector o rings pass contribution and buzz test.

Now the funny thing

When I fill the fuel bowl up with Lucas fuel cleaner. The truck doesn't flutter or smoke and will blow a wisp of black smoke on hard throttle instead of white

Any ideas?

Bump anyone?

Could it be air in the system still since I just swapped injectors?

i'll throw a bone. Check the icp plug for oil. If so, it needs replacing. Also, white/blue, to me, is raw fuel. Maybe the ipr is on its last leg. Only sure way to know, is get it on a scanner and watch the duty cylce, icp pressure...Sounds like the injectors are not firing. Also, do a buzz test.

I unplug the icp sensor and the smoke clears up a little bit but it still slightly there.

The plug does have oil on it. So I should replace the plug and icp or just the plug?

Replace the ICP, clean the plug.
