Good day i decided to check out this forum after finding it on google anyways

I have a 1998 ford e350 diesel 7.3 power stroke ambulance package engine my turbo is the mornings is getting worst each day.. after the truck is warmed up for about 10 minutes i drive out to the road and drives up the darn hill 20km then all of sudden couple secs after it will go to higher rpms.... and burst our alot of black smoke.....

Someone was telling me it could be the Waste Dump could be sticking?

Its a nice truck i love it but man i spent so much on this baby but love her to death.
