Hey guys, I have been a long time lurker and don't think I have ever posted. I need some help with my 2005 6.0. I have searched and read a ton, I can't seam to track down my issue. First off the truck has an egr
delete and the updated STC fitting with the stand pipes and dumby plugs. I also just installed a new injector in #2 because of a contribution code. Just cleaned the turbo when I did the STC fitting. Also did the blue spring and 6.4 banjo bolts. I am running a SCT live wire programmer with 4 inch exhaust. No custom tunes
The current issue is, when I try to get into the throttle at all it bucks and acts like it's not getting fuel, I changed that injector and the truck does idle better now and at cruise seams to be smoother, but it didn't fix the bucking. It does take off like crazy now with the new injector for a second and then starts to buck again. If I am super smooth with the throttle I can get up to highway speeds,and it runs smooth down the highway, but if I get into the throttle just a little to hard it bucks and hiccups
I have check FICIM voltage and also the ICP
Pressures. Both checkout good and I have also watched the scanner on the cylinder contribution codes and when it bucks it doesn't show any cylinders missing. I have also pulled the programmer and it still does the same thing just not as bad. I also just changed the fuel filters and oil not even 3,000 miles ago. My next step is to check fuel pressure at the bowl and pull the frame filter out and see what it looks like.
Thanks guys any help or ideas would be great
