Ok, so I have found this to be strange, but doesn't affect performance on my dodge. Last night I started it, (wasn't plugged in but it was 45* yesterday) opened the rear drivers side door and walked to the rear of the truck to grab some tools from work. The truck then coughs, and goes back to running normal. I walk back to the drivers seat, idle it up and it runs normal....it has coughed a few times before, just wondering if anyone knows what this is? :confused013: Any feedback welcome!!
