Plug It in....its a big displacement non spark ignition engine..if that doesnt solve the problem. i was told by a PSD mech. that he has tried many things to stop that even when plugged in..he changed the clutch on a truck and the shake stopped...so i dont know what to tell you if the plug in doesnt help..my truck does it when not plugged in for like 5 sec. in cold weather.

about like 28 and its a 6.0

im do not know much bout the 6.0 but i could tell you bout the 7.3. but i think it just might be that international is a little rough in the cold cause every international i have does that when its cold out side. try plugging it in

i plugged it in last night and it didnt do it guess it just when i dont plug it in... but now the check engine light keeps going on and off ah haha

Ford issues a TSB on this issue a while back, here is their offical statement from Dieselmann's website.

"94-03 7.3 Idle Lope on Cold Start:
Ford has determined that the engine loping on a cold start is a characteristic of the engine. They are recommending to use a lower viscosity oil--10W-30 meeting API service CH-4 or CI4--to reduce the condition. They also suggest plugging in the block heater when outside temperatures are below 30 degrees and/or waiting up to two minutes with the key on before starting the engine to allow the glow plugs to fully heat the cylinders. Broadcast Message 1050."

My 03 6.0 sounds like I got the nastiest cam in my truck. Thats normal especially if you have a chip. But mine doesn't do it if its plugged in. I kinda like it though!

You wouldn't like that sound if you knew what it was doing to your injectors! You guys need a lighter weight oil for cold temps. My truck doesn't do that anymore with 5W40.
