Intake gaskets are 1 day old. O2 sensors are reading where they need to be, I don’t have the numbers but it is stored in my Zeus, will check and report back, will also check the scan on the fuel trim- Josh Cushing

02 Yukon 5.3 flex missing, need help !!!!
ok like the title states I’ve got an 02 Yukon XL 5.3 flex engine with a miss on startup: Symptoms: rough idling,shaking. Crank the vehicle. Runs good for about 15 seconds, then starts to miss pretty rough. I can press the gas really high in rpms, problem goes away. Things fixed so far...- Josh Cushing
