I recently blocked my EGR and installed finger stick. The truck runs better then it did before the mod. However, at idle I have alot of white smoke coming from the tail pipe and you can smell the burned fuel and/or oil. I only notice the smoke at idle, especially when I come to a stop, say after being on the freeway. The truck does not run bad, if fact it runs really good now, and I have no check engine lights. Is there a possible reason for this, maybe the ECM is adjusting ? I am ok with it smoking, just want to be sure nothing major is wrong. Thanks in advance for any help.
