When was you fuel filter last changed? Only time mine will run rough is when i don't wait for the glow plugs. It's running smooth within 20 seconds though.
I believe the Inductive Heat Flash came out around Jan 2007. If the dealership has had the vehicle more recently than that, the upgrade - if you got it - should show up in an OASIS report. However, mine does not show up on the OASIS report - apparently because I took the vehicle in and said I had no complaints, just wanted the flash upgrade (I guess at that point it was not a warranty repair isssue).
I wonder what the current draw would be when the inductive heating was going on? This may be a way to tell. I have access to a clamp on ammeter - I may investigate this. There may be other ways, but I am not aware of them.
I wondered the same but I suppose I'll find out when it gets colder. I had the local dealer reflash my truck yesterday to address cold start issues. I still hear the injectors cycle when I turn the key. It wasn't that cold this morning and the truck still chugged on startup. After rough idling for a few seconds (sounded like one side of the engine was running and the other wasn't) it smoothed out a bit, then raced up to about 1200 rpm, fluctuated back down to 600 rpm, then acted normal. I'm thinking ICP sensor.
i couldn't find the plug on my 04, added a heater to the lower radiator hose for this year. Do all of them have a block heater?? Had a stock one on my 7.3. Even had a stock Motorcraft one on a 86 mustang convertable that was produced for canada. (kinda ironic to have a block heater on a RWD v8 conv)
They all have block heaters its right next to the starter motor.
Parked my 03 F250 6.0 (80K on her) at the airport last Sunday morning and jumped on the airplane(s) for a week in Denver. While I was gone, it snowed a little and obviously the temps dropped into the low 30's / high 20's.
I got back today (Thursday) at @3PM...temps were in the low 50's. I started her up and MAN OH MAN she didn't like not being plugged in while I was gone. She blue smoked...that's normal, but for about 3 or 4 minutes it sounded like she was running on about 5 cylinders. About the 4 or 5 minute point she smoothed out and seemed to run normal.
My question is, should I be concerned?
Normally when temps drop down this low I plug her in overnight and she fires right up in the mornings....regardless of temps. So like any concerned parent...I'm wondering if I should be concerned or this normal for leaving one outside in the cold for several days and then just firing her up.
Ok, the latest update...I've plugged her in for the past two nights...and she's fired right up the next morning. No rough running...just the normal smooth diesel growl.
SO....I'm guessing the overnights in cold enough to snow temps were my original problem. Time will tell.
