Alright guys just had EGR delete, head gaskets and ARP studs, and new oil cooler install on the truck in my sig. The truck drove great the first couple of days. Yesterday got in started the truck and it almost fell on its face; ok then it warmed up and was fine started going down the road and it seems to have a loss of power. Come to a stop sign and it has a little flutter at idle... this morning I disconnected the egr valve plug and the truck seems to be idleing fine now. My question is should I leave it unplugged? Will leaving it unplugged cause any damage down the road? Or should I do something else ? Sorta confused here thanks for any help.
