Sorry for the cross post, but I am looking to see if anyone in or near Las Vegas has an AutoEnginuity that we could scan the truck with.

I am 99% sure on the injector failure as this happened to me about 8 months ago and the symptoms are identical , scary knock, lots of black smoke, the the white bluish smoke at start / idle.

I will have the truck home tomorrow when the sun is up and will know more.

Thanks

Troy
