When I am pulling my 5th wheel down the road our truck looses power and blowing a ton of smoke when we accelerate, will not shift into passing just blows smoke , without the trailer the truck runs great and only smokes a bit, dealer can't rap their head around cause, no codes, had particulate problem 1 month ago they had to regen, we are stuck on our trip. ..help

 

Do you have a Boost Gauge? Seems like your turbo may not be delivering enough air for the load. Could be an issue with the turbo, or leaking issue with the intercooler or the flexible tubes. Sometimes, if the flex tubes are cracked, it only shows when under pressure and is difficult to find.
Back to morning brew . . .

 

REGEN? truck is blowing black smoke then DPF is no good, (cracked internally) , Over fueling most likely injectors are stuck, is oil level overfull mark? Air filter not plugged? no leaking boost hoses? you may hear a whistle noise when under load. What does boost pressure show on dash gauge when WOT? All sensors are plugged in and locked? MAF, TMAP, FCA, Fuel pressure sensor, no codes setting? Last truck I had with this issue customer set a shop rag on air filter, then installed air filter cover. You know what happen next.

 

thanks for replying, no boost gauge on truck, the dealer is still doing tests, but no info yet.

 

they tested fuel, injectors and all sensors all read good . No boost gauge on truck, will run great without trailer, but won't run for crappwith load ? Lost. ... truck has thrown no codes out. .. new air filter and fuel filter and fresh oil change.

 

they checked intercooler and hoses can't find anything wrong there.

 

What was the outcome ?
