This motor (2008 with stage 1 PDI delete in a 09 Prostar) started after running a few weeks back. It runs for 5-8 seconds after shutdown as well as running really rough in the idle kick-up mode (a few seconds after start-up when the idle kicks up to the 800 rmp range and continues running rough till it "warms up" (60 to 120 seconds). My mechanic couldn't get insight to pull any codes and thought it was an injector, so I had all six rebuilt. same issues. replaced the stop solenoid, same issues. Took it back to the PDI shop that did the delete, they also could not find any codes but assured me it wasn't the ECM. They indicated it was likely one (or more) of the fuel actuators and explained the expensive process of testing them. Thought I would post here before coughing up a couple more thousand dollars for opinions of the diagnosis. also, if I drive the truck with the after run problem (runs great going down the road), how badly could I damage the motor? Thanks for everyone's help
