'01 Chevy Silverado 5.3

History: Had a Maggie on it for a few thousand miles then put back to stock minus the EGR. Ran great for two weeks after the Maggie was removed until yesterday when it started misfiring and went into limp home mode SES blinking.

Checked all the wires and everything looks okay. Re-seated injector connections - no help.

Scan and tune attached any ideas? I'm at a loss.

Thanks in advance!

Damn, I wondered why everyone was being so anti-social hehe. It's fixed - took it to the dealer and they replaced the busbar in the under hood fuse box that powers bank 1 fuel injectors. Thank you Warranty Direct extended warranty!
