Loose Injector Wire Under the Valve Cover?
2004.5 F250 SD XLT 4dr 6.0L
CAI, 4" Straight exhaust
EGR Delete, 6.4 Injector pump
Coolant filtration system.
New injectors al around
New ICP, New IPR, New Oil Cooler.
Recently Bulletproofed on ARP head studs, and the stock Head gasket,
New injector harness and FICM from DieselTech Ron
SCT tuner, running innovative diesel tunes. EGT Sensor
37x13.5r18 nitto trail grrappleers
I do not have a bad injector, or a bad ICP. The Head is not leaking nor is the potentiometer [TPS] or CPS bad. All of these things have been replaced. Even the injector harness has been replaced. The only thing I have not done is remove the valve cover and making sure all the injectors are tight.
I recently had a contribution error on cylinder 8. Hence the extensive ends I went to above. The new harness and FICM connectors fixed that part of the problem, but apparently the bucking and stalling were not related to that.
No codes are coming up.
I'm running an SCT tuner with Innovative Diesel's Extreme Street tune.
The truck runs fine UNTIL I REACH OVER 60 MPH. At 60+ it starts bucking until i get below 45-50, then I can get back up to speed but no faster than 60. If I let off it real fast while bucking, it stalls. If I rev it at high RPM i can keep it going but once it shifts down, its over and sometimes even stalls.
This problem first started right after I swapped out my Banjo bolts for the 6.4 banjo bolts. BUT! it worked fine for a week or so, and then started the cylinder issues. So I thought they were all related. Apparently not. I have researched the crap out of this and tried everything. My FICM is new from Diesel Tech Ron [love this guy]. The other harness is in bad shape. I had to replace the end connector when I did the injector harness [don't recommend it, those little wires are a pain...] a lot of sensors run off this other harness including the IPR. Could the IPR be the culprit [its new also from the head replacement]
Any suggestions? Please help. I commute... [At 60 mph lately...]
Sounds like I have a loose injector wire under the valve cover.
