Yes traction control light, flashing engine light. Could there be air trapped in the fuel rails? Possible to put the wrong plug on an injector? Everything looks legit, no leaks, good oil pressure.

I would go back and double check everything you touched, including your Peter if you took a leak while working on the truck... just to rule out anything.

Make sure your air intake tube is fully seated and sealed properly.

Did you remember to plug in the main harness for the coil packs?

Is anybody here familiar with doing this valley cover gasket job with the AFM solenoids under it?

IS IT POSSIBLE, replacing just the perimeter gasket and NOT the gaskets for the solenoid oil ports underneath has this thing ****** up and misfiring?
