2005 Silverado

I have looked on efi live, have not been able to find anything helpful.

I have done a few Rafig sessions and idle VE stuff.

The problem i am having is on EVERY start up it will idle up like normal but then the rpm will drop off (idle is 750, cold it will drop about 1-200 rpm for about 3 seconds, operating temp it will drop like 3-400 rpm for 3 seconds) it does not die, it just dips down.

I have done alot of research any help would be appreciated.

RAFIG is In Gear
RAFPN is Park/neutral
Or did you do both?

So when you start the truck everytime hot or cold it flares,Idle falls below 500 and back stable?
If your RAF IS in line,then look at your startup> friction airflow decay and also decay delay if needed..

It does it less when cold, but yes EVERY startup it will start up, idle high, then drop off like its going to die, but doesnt actually die. After it idles fine.


Also i have done RAFIG, I am not to worries about RAFPN because that is only when i have the clutch in. (according to descriptions)

do you not have to push in the clutch to start the truck?
