Warm up a 7.3 ?
7.3 has started running real rough, coughing and spitting like its fuel starved. Runs fine when 1st cranks up, just when try to take off before it warms up will it go thru its spasams.
Stop the motor and crank it back up its still a little rough but will eventually smooth out and run fine. After its warmed up.
I live in a warm climate, it happened yesterday in the middle of a 70 degree day.
I usually let motor warm up for a minute or 2 before taking off but it seems to take a good 4 to 5 mins now.
Fuel system?
Battery voltage?

It could also be a glow plug issue. I know you said 70 degree day and all that, but the glow plugs do play a part in warming the engine, even at those temps. Have you checked the relay to see if it is providing voltage?

I'll check the tech folder and see what it says.
Thanks
