rough idle
i have a 2002 cummins with a vp44 hot rod injector pump, a bd deisel max flow pick up pump, afe cold air intake and intake horn, edge ez, and recently added smarty s-03. the rough idle started after the vp44 hot rod pump. it smooths out with the a/c on when warmed up, and with the a/c off when cool. any help would be greatly appreciated.

yeah. i have a bd max flow that is acting up, the low pressure fuel gauge varies from 5-30 psi sporadically jumping around. the replacement will be here tomorrow. hopefully that fixes it. btw they said the new pump needs to be installed motor side up and fuel side down to prevent problems.
