Like the title says I've got a 99 2500 been chasing this issue pretty much since I got the truck almost 2 years ago. Long story here I've dug and dug into research on it. Looked at other forums, looked at other pages, seen what worked. I even fixed a few when I worked at dodge by relocating the ground across the radiator. That's what led me to this site when I found out about the alternator AC issue. It made perfect sense seeing as my ECM has a bad microprocessor also. I tried all those bogus tricks. Nothing can seem to fix my truck short of a $3000 manual swap. Only one that really helped was cleaning and replacing bolts on battery terminals for about a week then it came back. I recently changed the diodes having 0.016vAC. I did the wiring mod in the process. I noticed a huge improvement. I'd say 95%. I'm still getting it after I set the cruise it'll do it only once right after vacuum grabs throttle and usually if I accelerate moderately from say 45-55 or 55-65 it'll kick out a couple times. Light throttle won't do it. Feels like same amount of throttle amount every time. Monitoring on scan tool the TC solenoid output in the PCM is still dropping out so I know it's not TC or solenoid. Tps volts look normal on the graph also. I have no doubts the tps volts is filtered so I may not see any system noise but if it lost voltage I'd see it on the graph. I'm wondering if I have an actual APPS issue. If so are aftermarket ones any good? Their electronics are usually junk
