Need Help
 

i have a 2008 ram 3500 6.7 just did the oil filter and fuel filter about 300 miles ago barely made it home. now i have no power at all and pinging like crazy white smoke no codes it did this before the maintenance. but not this bad i could get it home. Thanks for any help

I would check the fuel system to see if air is getting in some how.

update
 

if i unplug the throttle valve connector it runs with no sputtering but i have a wierd smell out the tail pipe and no turbo wind at all Thanks for the help 97 cummins
