05 blazer 4.3l. Air temp sensor /ecm ?
Finally got her to start up , runs uneven and rich , fuel trims both max negative to -27
all sensors showing normal operation , it will start after inlet it sit a minute or 2 and idle fine until I try to drive it then fuel trims drop negative and stay unless I bump the throttle in neutral they will the. Normalize but then drop rapidly .
