Anyone experience this yet? Concerning issue...

Well I've finally been hit with an issue that I can't chase down a resolution to. When I go to fire up the truck it either 1/ Doesn't start or 2/ starts and immediately dies.

Yes - I will scan the codes later but wanted to see if this was something anyone else has dealt with already.

FWIW I do have a JB4.

Does it run ok when you use the remote start from the key fob?

My guess is a boost tube has come loose, or one of the emission hoses had popped off causing a boost/vacuum leak.

Does the exact same thing, either doesn't start or shuts off after a few seconds.

Just watched the video. Might be a fuel/air related issue due to the sound as it sounds like it’s starving for fuel or air. Maybe a bad fuel pump, clogged/loose fuel line or something is not connected properly on the intake side.

Code is for a rich condition, so I think you're right on the air front.

sounds like an air leak somewhere.

I just got a cel and codes were for rich conditions both banks. Truck seems to run fine, but does feel a little sluggish.

Thankfully my CEL hasn't returned. interested to see what you find out the 2nd time around

Haven't had that but my truck did stop making a left turn when light was changing. And stop I mean abruptly like it was going to hit something although the cars didn't start moving yet. Shocked me haha came to complete stop then got going. No one behind me thankfully trying to race the light.

Hopefully you get some info from your dealer today

That's because you have AEB enabled...disable that shit, it's a killer.
