No Remans there is a very very slight knock right now and no codes are being thrown. My Injectors went straight for the box after being tested into the truck. I have no idea what to do any ideas

 

So head or head gasket issue for sure coolant is pressurizing and also combustion coming out. So that's definetly got to get fixed but I have another issue. While driving I cant get it over 2000 rpms and 40mph it like kills itself and looses all power any ideas please help?
01 LB7

 

any engine codes?

 

Limp home mode will limit the rpms to 2000 and reduce fueling. Need to pull the code to see why

 

No Check Engine Light and no Codes that pop up the only code I have coming up is P0463 which is my fuel Gage. Changed the fuel filter and still the same problem. Would my head gasket be causing this issue?

 

Interesting. Any condition that would cause limp mode should have a code. I have heard of rare situations where it ecm is running in limp mode with no explanation. I would clear all codes including history (make note of them first) and then disconnect the batteries for about 10 minutes. See if this resets it

Head gasket shouldn't cause it unless it was so bad that it was... cant think of anything that would do it then ether. Hmm, got to think this one over

 

prob a soft engine ovrboost code, ive had that happen before

 

What exactly is that the soft Engine overboost code? And my trucks completely apart right now pulled the heads and they are getting checked. What about my injection pump any clues on that? The Lb7s don't have a high idle switch do they?

Could this also be the issue? Should I just go ahead and consider doing this as well since my trucks completely apart right now?

 

you can install a high idle switch, the shimmod isnt necessary unless you tune your truck to run 26k+psi
