Hello Everyone Looking for some Pointers here. I have been Battling this for awhile! I did find a Vacuum Leak, Fixed it. The Truck is still running very Rough at idle! When warmed up or cold. Idle Seems to get a bit worse once the truck is warmer. I did try a Different Mass Airflow Sensor That didnt seem to change much. I have the Torque app Along with a bluetooth OBD II Reader. I Took some Screenshots hope you guys can help me out. Someone Was Leaning towards the 02 Sensors or possibly Fuel Pressure?
