Trying to get this truck to idle without a lope. The spill ports are plugged on the injectors and from what I understand I need to lower the amount of fuel at idle. I can do this with pulse in the FICM but I am wondering if there is a cleaner way in the ECM. I can't for the life of me figure out what is controlled Fuel Mass Desired at idle to try and lower it that way.
Injectors are a Warren 155/stock nozzle.
I lowered the pulse in the FICM and got the lope to go away but as the truck warmed up it came back. Any assistance would be greatly appreciated.
