Hey everyone so I have this rough idle problem with my truck that's been bothering me since I've owned it and would really like to fix it.
My rpm will not stay constant at idle it fluctuates about 30rpm every second in pulses causing an annoying vibration I can feel in my seat and I can hear it sounds like crap.
This happens regardless of engine temp, drive, park, neutral, it always does it. I know this is not normal because my other 7.3 idles as smooth as butter.
Other than this annoyance the truck seems to be running great with good power.
I have new fuel filter, air filter and fluids. Also this is not caused by water in my fuel that's the first thing I checked.
I have also tried unplugging the EBP sensor and idle remained the same.
If anyone has any suggestions I would greatly appreciate your help
Early 99' 7.3/auto
