Sputtering
I had a bad injector so I just replaced them! ! I have a 1995 2500 4x4 Cummins 5 speed! At high rpm’s I’m getting a sputtering? Anyone have any info on what could be causing this! Also the temp gauge rises then drops while driving

How did you diagnose bad injectors? What symptoms did the truck have prior to replacement?
Tell us about the truck, miles, any mechanical modifications, etc...
Where did you get the replacement injectors from? Are they a stock replacement or aftermarket? Manufacturer, size, part number if you have it.
We need more information to help you out.
Sputtering could be caused by a long list of things;
Injector pop pressure
Injection timing
Loose intercooler boot/coupler
Blown/torn intake manifold gasket
Loose hardware
Failing lift/supply pump
Blown headgasket
and the list goes on...
