This just got back from the tuner. It's my bros truck, i found out that when the truck is hot it starts up, idles above 1000 rpm for a few seconds then dips low, then it stalls. The rpm still dips on a cold startup, but not as much to cause a stall.
In the log i have included, i try to start the truck when its already up to temp. it starts then stalls, i attempted to start it again, it starts, then the rpm dips almost as if it was going to stall then it recovered. I then turn it off again and restart, the third time it stalls again.
If i assist the start by adding throttle it will start and run normally after a few seconds, then i can drive it around normally with no stalling or idling issues.
I Would like to know if there are any suggestions on what may be the cause. Thank you for your help!
