stumble...isc
Recently replaced the gear pump and injector pump (rebuilt) on my 2008 pete, with an isc. Previous to the new pumps, the truck had a stumble in the top two gears around the middle of the rpm range. For a couple of days following the pump replacements, the stumble was gone, however its returned. Any suggestions as to what to look at next? No active codes, fuel rail pressure is good, injectors/lines/quill tubes all replaced last spring.

Thanks!
