Runs great until it heats up (normal Range) then idles rough ,when i i hit the accelerator it hesitates and stalls out

 

Let's get that OBDII code reader hooked up! We want to know what codes you have, if any. We want to know if the coolant temperature sensor is working correctly. Coolant temp reading is important to fueling. We want to know if the O2 sensors are working, switching on and off normally. Fuel trim numbers, etc. etc. You can see what the ECU sees via the code reader. It's a great place to start.

Also, look for any physical issues with the throttle linkages. The bushings and nuts must be tight and both banks must open up equally.

 

Yep, without codes too many possibilities. With codes or lack of will narrow down where to look. I spect it will be an easy fix.
