Truck Specs: 2002 Dodge Ram 2500hd, Std Output 5 speed. Mods: BD-Diesel Flow-max Lift pump, BD-Diesel Exhaust Brake, AEM Brute Force HD air intake, Bully Dog Outlook with Performance Enhancement, Stock Straight Pipe. Recently my truck started intermittent miss at idle, and stumble during normal acceleration, under load / no load / from start.Truck has plenty of power, and good fuel mileage, Both conditions are random with no codes given, other than above exhibits no other issues.I've had issues with the bully dog outlook performance device in the past, causing stumble but goes away when I place it in stock mode. From what I've read on line in several places, it's been suggested that the computer on the vp44 might be starting to fail (ECM I think ?)Lift pump pressure is good. Any thoughts as to what might be going on (vp44,mpa, IAT)?Thanks in advance,Tony -
Can the idle speed on a 24 valve 2nd gen cummins be adjusted? If so how? My truck idles at 740-750 rpm, I would like it to idle around 800 rpm so it don't die when shifting into drive. The truck has a Low Stall TC and it is causing the truck to die when shifted into drive. If I hold the rpm to around 800 it don't stall. Does it warm or cold. Yes, fuel pressure is there (17.5), CKP was replaced 15 months ago, IAT and MAP are new, grounds and batt connections are clean and tight, batteries are well charged, alt is putting out 13.58 volts at the batt.
