2005 Dodge 2500 Diesel idle fluctuatung

Post by mjensen »

I am having an issue when I first start my truck. The idle will fluctuate up and down +/- 100 rpm and my battery gauge reads low. After about 2 minutes the idle will settle and the battery gauge will read properly. It almost seems like the ECU is stuck in open loop mode. After the 2 minutes the truck runs fine and has no other issues. It didn't start until I loaded the predator to the truck. Any thoughts on this?

it will always start in open loop if cold, it takes some time to heat the O2s to go into closed loop.
