You need to do some diagnostics like check for codes, CC test, balance test, maybe even compression test. You said smoke smell was distinctive, is it fuel? I would assume so. Are you low on power? Does the engine have a miss to it?

[Strokin30]

Yes it has lost power and sounds to have a miss to it!

Without this information, everything is just a guess.

Check fuel pressure also.

Also loss of power and sounds to have a slight miss! When cranking over it seems to hit then crank hit then crank but it will start up and when u first start it it wont knock or smoke then after about 30 sec or so it starts knockin and smokin! Its definately fuel

my programmer says it not throwing any codes

No one else has anything on this? I am thinking injector or O-ring
