Where to look now? Truck is an 06 LBZ....all stock. New fuel filter and filled up 4 days ago.....just started coming on while ago. Cleared it off with EFI, but after the second time truck was started, it came back on. I checked it again with the handheld, but no DTC's found, it says......cleared it again and off I went......came back on the next time truck was started. It runs absolutely fine, but the light is annoying......Thoughts?:)
