Default SES light
Pulled the car out of storage a few weeks ago and its been running great with the LT headers. But I was drivin it today and the SES light came on. I plugged in the OBDII scanner and i got a PO140 code. The car has 02 simms so i have no idea what would make it come on. Thanks for any help

Well just stating the obvious but did you double check your sims to make sure they're still plugged in and none of the wires got burnt/pinched??
