Be merciful, I'm an idiot.
Ok... I know what I need to know is on here somewhere.
I've searched a bunch, but don't know enough to know what I'm looking for.
I'm pretty good with a gasoline engine, but kinda ignorant with diesels.
got "all the tool in the world" but only a code reader, no real scanner.
no stealership nearby but a few "good" diesel shops.
I got a great deal on a 1999 7.3. Knew it needed a little work but couldn't pass it up.
280K long distance haul (no load) highway miles.
excellent service records - the company takes care of their trucks.
Really clean underhood - no leaks.
uses zero oil, 20 mph average, 26mph or so on the highway (checked it myself - was told it was geared for running, not pullin'- sounds reasonable to me)
absolutely no smoke at all, a little fog on a cold day, but just no smoke - I was told to be surprised about this.
I live in south GA, so our "cold" is nowhere near what I read about others' "cold"
if that's enough background...
I'm calling it a "miss", what else can it be? with a cold engine (first start of the day) I got the usual lack of power and clatter and stuff others identify. power returns when it gets to operating temp.
when its warm, I have a "stumble" or miss (vibration) at 40 - 60 mph or so - at a gentle cruise - unless i'm into the throttle. usually around 1000 - 1500 RPM. It's better around 2K rpm. I have an occasional "miss" around 2k rpm, but nothing common nor regular.
Idle is 90% good, occasional misfire if you listen long enough.
no CEL. and the ICP sensor-thing came out clean (not oily).
again, no smoke at all.
I'm going to clean the EBP and pipe apparatus today.
what do I need to be looking for on the board?
sorry so long, but wanted to give all the info I can for you "smart guys".
