So I just replaced all then injectors in the truck as they failed testing I'm still having issues. The truck wants to accerlate by itself and bucks like crazy under any throttle. It idles fine. I'm lost on what's happing. I attached a video. I get to speed then let go of the gas and this is the result

 

What CEL codes are being thrown?

 

I pulled
P0217 decreased engine proformace due to engine overheat condition

P0192 fuel pressure sensor voltage too low


The engine tempature gauge never went above regular operating tempature however

 

I would check the following

1. Both battery connections and grounds
2. Fuel filter- make sure it is clean
3. Rail Pressure sensor connection (this is in the top of the fuel rail. Make sure it is dry and maybe use dielectric grease if possible)
4. Fan clutch connection- although gauge didn't get above warm check this- drivers side lower radiator. Seems like it could be an electrical thing...shocker.

 

Okay battery terminals are tight and clean
There is a new fuel filter on it
It's an after market electric fan and it's running as it should be.

I took off the fuel pressure sensor harness and it was dry, I cleaned it anyways and put dielectric grease on it and now it runs worse than before.

 

any progress?

 

no none at all I'm stumped as what it could be

 

Check your apps, etc.

The APPS you can turn the key to on but don't start, push the accelerator all the down, and slowly let up on it and you will see the CEL flash several times to acknowledge the calibration.
