Rough Startup cured. Blown Head Gasket.

My Haynes manual says the 17 cam bridge to head bolts are also torque to yield, and they recommend replacing them. I did on mine, but the video clearly shows they did not. The video I believe shows they were able to complete the job the same day they started it, but I don’t believe they did it in only 45 minutes. LoL.

My last remove, teardown, and reassembly started at 9am, buying new head bolts at 12p, and drove it home at 5:30. That was with competent helper and a little moral support.

 

Those guys seem kinda fly-by-night. But still, lots of tips.

 

So we just replaced head gasket but now it won't start. Throwing sensor codes....anyone know what we did wrong?

 

Double checked all the sensors are plugged in. MAP sensor is one I've forgotten.

What codes btw?
