Kinda feels like I have a small cam. Anyway, the fuel pressure goes up and down a little. It has done this more since I removed the egr. I removed it because the thing was clogged and was throwing a code. Damn GM.

 

Fuel filter?

 

clogged injectors? Bad fuel pump?

 

I am going to start small and work my way up

 

I Had The Same Idle And Fuel Pressure Problem. I Ended Up Replacing The Fuel Pump After Doing An Injector Service And A Fuel Filter.

 

Sounds like a fuel pump problem...

 

sounds like a fuel pump but start with a filter you should change if you change the pump any way
