As the title says, my truck has a intermittent surge in the idle. Idle jumps up 50-100 rpm. Sometimes at a stoplight in gear and truck wants to lunge forward. All systems check out except the FICM. (44-46v) on cold start up. Goes up to 48v occasionally. Brand new (reman) injectors. Brand new icp sensor and pigtail. Truck is running 100% better than a week ago prior to injectors. Idle is extremely smooth and plenty of low end and high end power. Engine is running amazing! Just this stupid idle surge. :dunno: I have the 58v FICM coming from swamps. Should be here monday. Do yall think the FICM might help with this surge? My only other thought at this point is IPR. ICP and IPR duty cycle both check out. I'm hopeing the FICM will solve this and I'll be done spending money for a while. Any thoughts or suggestions? Thanks!
