Running diagnostics on 2005 Ford F450 with 6.0 Powerstroke. The MK808TS says the desired engine idle speed is 4000+ RPMs. Is there a way to use the MK808TS to adjust that number down to the correct 650-670 RPMs? Everything else on the scanner is reading in the correct specs. I added a pic of what it’s showing on the MK808TS. Thanks in advance for ANY and ALL help.
