Having stiction issues i think ,rough start in the mornings, bluesh-white smoke when taking off, no power,about 10 mph then 20 in 2 mins. 30 in 4 mins. then along about 5 mins. smoke stops power comes back ,runs great but jerks about 45 mph and then smooths out, okay the rest of the day,morning temps about 40 f ,ficm checks out okay,had a dealer flash in late 2010 since then replaced hpop,egr delete,and replaced complete engine harness , have another question, heard about a new flash that adresses stiction- any problem getting updated flash from the dealer with egr delete,egr still pluged in and no light on

 

whats the readings on your scans ,, ?could be IPR is the egr closed and seald off ? could be a glo plug .cyl switch cyl turrn on.

 

I would double check my FICM.

 

not throwing any codes,koeo or koer

 

should i test ficm volts when engine is hot after driving or does it matter

 

If your problem is when it's cold, then I would be concerned mostly with voltage at that first start of the day. Quite often if the resistor solder joints are cracked in the FICM, once warm they will close and the voltages will read fine.
