i have been trying to get the truck to hit the correct idle mixture after start up but will start up and idle very rich for idk how long and then there will be a time when it ran for about a minute or two and got shut off, restarted and idles a tad lean like it prolly should for the cam in it.

great response and just amazing off idle power when it hits that tad lean idle and hits the regular correct AFR then under power. Also this is in open loop, the truck runs amazing like this at 90 degrees or 10 degrees but as soon you put it in close loop it goes nuts. i believe it goes very rich under power where it startes to almost choke its self and kill the motor. could the o2 sensors be old and bad and to slow creating this? but most of all how do i fix my idle??
