Idle Problem


Recommended Posts

Posted

2004 Sierra. I had to take my battery out over night. I put it back in this morning..at idle, the rpm's randomly drain from 5 to about 2. Up down up down about every 10-12 seconds. No issues while driving.

 

Thanks in advance for your thoughts.

By removing the battery, you basically reset the PCM... Drive it some and I'm sure it will go back to normal :thumbs:
