been seeing this for awhile now, when engine is warmed up after stopping for a time when i get back in and fire up i get a good puff of black smoke, truck has 190k on original injection pump, no problems with idle or cold startup, any thoughts? thanks in advance love this site

Does this happen when you idle it for over ten minutes?

cbschmidt

no, only when it has sat after running, after hardware, ammo store, bakery, etc get back in, crank up, poof off we go

Could some of the injecters be leaking down when shut off?

I always get a puff of black smoke when the engine is cold, but only sometimes when the engine is warm. I just had new Bosch injectors installed last summer. That helped the problem, but it's still there.

Mine puffs a little black when warm...Even more if I have my foot on the pedal before I start it..

noticed the other day that i was giving it to much pedal upon start up, less pedal = more cranks from starter but cleaner exhaust. thanks for the feedback, love this site
