Hello,

The white smoke/steam is usually a good indication of a blown head gasket.

Pull the plugs and inspect for water/coolant on them.

Changed 5 of 6 s/p and no water or coolant. Will change 6th once I figure out how to get around steerind rod. All plugs were fouled. Starts a little easier but idles rough and still have smoke and gas at exhaust. Any ideas are appreciated.

Ok, once last plug is changed and checked we'll go from there.

Were the plugs fuel fouled? If fuel fouled could be leaky injectors, bad fuel pressure regulator or weak fuel pump.

Plugs all fuel fouled and black. I was leaning to FPR, but not a mech. And everyone thought I was insane. Will replace last plug during daylight(have to lift steering rod). Will keep u posted. Also having a mobile diagnostic coming tom.

Tech came, ran full diag. Fuel sys. And all, and said #5 and #6 injectors stuck wide open and over fueling. That was the only codes showing. Replaced injectors and still have same problem, gas in exhaust and stalling. Is it possible pcm is shot?

Well, I was thinking more the Cat than the PCM. With all the unburned fuel going through it and it I'm sure has overheated, that it is clugged.

You can somewhat check it by removing the O2 Sensors before the Cat and see what happens. If it runs fine then you know it the Cat.
