So Im gonna make my first post about an issue i have been having for some time now. I did alot of mods myself, or had done by a shop to lesson the issue, yet it stuck around. Ill give a low down on what I have done to the old gal, as well as give some symptoms to the problem. Aaaan Awwaayyyy we Goo.
Main Point One: The mods and aftermarket parts.
shes a 96 2wd 7.3di, when I got it used from a gentleman who in my eyes was a good ol boy who took care of his stuff, it had maybe 268,000 on it and had gone through a few clutches during its time, which really was a result of the heim joint at the clutch pedal, so that got replaced and chucked the dual mass and went with a single mass and clutch from south bend, then it also got a new oil cooler, a set of baby swamps, hydra chip, forced air intake, Mishimoto RAD, Beans D66 Turbo, EBP
Delete, 3inch Down-5inch Out, new mechanical fuel pump, and rebuilt fuel bowl with all the goodies to go with it, new tanks front an rear, CPS
, and has either had t4, or a high tbn
Amsoil w/ Archoil additive.
Main Point Two: THE STINKING SYMPTOM
Ever since I acquired the greasy bastard I noticed a small idle blip. Not one that seemed to concerning at first. It would dip maybe 50RPMs and back to idle, but only at a stop or idle. Then in 2015 as I was driving down the ALCAN highway through canada i stopped of for some fuel and when I went to crank it over I got a Crank/No Start. THIS WAS SO FRUSTRATING. It took me all but a day stuck in canada to get the sucker running, the reason you ask - fuel selection switch. So I flipped the switch from rear to front and she cranked right up and started. No I never did look to far into this being Im always on the run from state to state working, so I just kept driving, but again at idle this tiny blip of 50 or 70 RPM bounce would start up again. So as im making another run from alaska down I stopped in Tacoma, Wa. With my hard earned cash from the state of Alaska I stopped into a shop known as Northwest Custom Diesel. I had them drop in the swamps, turbo, and tune it. This I thought to myself has got to fix that idle issue. Well after a few months it returned and still does it sitting at a light or at idle. Now let me say it does not do it all the time, I find if i keep that turbo spooled up it hardly does it or doesnt do it at all, but if its a driving miss daisy kind of day I see if more often. Let me also say it will dip and then return OR sometimes it will rise and then return. It really is intermediate and can just leave me standing there staring into the engine bay and scratching my butt. If anyone can shed some light on what I could look for or maybe a route to diagnose it would be GREAT.
If you have questions just ask, Im sure i left out some hefty data iv collected over the years trying to figure this issue out but Im trying to not bore yall with my writing. Im good for just rambling on.
