New guy from Oregon with a problem today
 

I'll do so searching, but if anyone wants to chime in directly I would appreciate it. 2006 Ram 2500 all stock with the exception of Exhaust, cold air intake, and Edge EZ. 243k miles....

Sooo driving back home to Oregon today from Nor-Cal all is doing great as usual until major run ability problems. Here where the conditions. Cruise control set @ 70mph, 90 degrees outside, just above 1/4 tank fuel remaining since fill up in Willitis Ca. Running empty NOT hauling or towing.
So here's what happened. was blasting along, than than a huge kick like a massive cyl dump miss, than starts bucking and missing bad, starts pinging real bad, I cancel the cruise and give it 3/4 throttle the truck takes off into run-away mode gets to 85mph , large black smoke. I was about to shut the key off when it stops and calms down, but still missing. So I look at my traffic conditions and decide to lay into see see what happens, I go WOT and get a huge plume of black smoke again and massive detonation(pinging), bucking, cutting out, and again run-a-way. If i brought it down under 60 and low pedal maintenance she cruised fine, but the moment it's put under a load or heavy pedal all would start again, I was able to make it home, but there is a problem. No check engine light, no funny warning lights, water temp normal, oil level normal, and oil pressure normal.
So If anyone knows of a thread here on this please share with me or let me know your thoughts. Thanks

Check all your boots, pipes and intercooler. Also look for exhaust leaks.
the oil pressure gauge is fake by the way.
