ever since the temperature outside has dropped from summer/warmer temperatures, the engine has started stumbling @ idle during a dpf burn off.
the tach doesnt show a stumble but you can definitely feel it. the engine idles very rough.
when it was warmer/summer temperatures this was not the case.

is there something possibly to adjust to help smooth it out?
i guess this is just another reason to do a dpf delete but i dont have the extra $500usd for a delete pipe right now. 

Pardon my ignorance, but define dpf. My brain can only store so many acronyms.

yes, regen but not at idle seems a good solution. maybe i can find something about it in my damos.
