When I first push the gas pedal after sitting at a stop while the engine is hot the truck stumbles a bit like a rough idle. Any ideas what this new problem is?

Thinks it's fuel related? Filter, bad fuel, ect.......?

Ill check my logs and see when I changed them last. Any other things to check or look for?

Check you injector balance rates also.

Any white smoke?

No white smoke. It does it only when at normal op temp. It also only does it for the first 1-200 rpms of acceleration. It does it while rolling to a stop and also while starting from a stop.

Basically anytime the rpms are at 1-200 above normal idle. Could this be an mass air flow thing?

Its getting worse by the day!


Any ideas??

Did you check the balance rates on the injectors yet?

check balance rates/DTC's... Change fuel filter. Are you running any additives in your fuel? the ULSD is some nasty stuff. Get some outboard 2stroke engine oil and add one ounce per gallon of diesel..
