    In the scan tool, select the PID's for the diesel called something like "balancing flow rate" or "balancing cylinder rate" there's one for each cylinder, when you connect to your truck's ECM and start monitoring the data, the bad cylinder should have a substantially different balance rate...I believe they should all be within +/- 4? Something like that, that'll get you pointed in the right direction hopefully. Are you familiar with how to select PID's and log data? If not we're all glad to help my friend... that is at least if your full name is "John Deere" tractor....nothing else can be called a tractor haha

    Yeah, it took me a solid year to get somewhat good at this. I've still got much to learn, the biggest thing is don't be afraid to ask questions! And make changes in small increments so you'll know what affect they have first.
