a question about my E350 w/ 7.3 PSD. It has a Quigley 4X kit on it and DPtuner 60hp econo tune fyi. I know a Cummins but, nothing about a 7.3
what would cause it to surge at idle up and down. No, rpm gauge but, it's not revving a whole lot. It's almost like a Cummins that has the heater grid cycling cause the voltage to drop but, is the power instead.
Not sure which trans is in it but it only has 30K on it. Sometimes when backing up, the engine cuts in and out like is looses power then regains it. It's prevented me from being able to back up at times because it won't build the constant power to do it.
sometimes, if it's been sitting for while and I go to start it... it won't start. It's like it floods out and can't ignite the fuel. It will blow tons of white smoke in the process. If I let it sit for a while longer... it will start right up. I've replaced the glow plugs but, not sure about the GP relay. The wait to start light comes on and stays on for a good while before going out which lead me to believe the reply isn't having a problem.
I plan to dive into the 7.3 bible but, though I could get a head start here
