Ok if I have a fully dead injector is it gonna have a massive effect on performance?? Or is it soooo incredibly low on power because I did a egr delete and haven't turned the egr off yet but floored it in the 04 6.0 just did egr delete and oil cooler and floored it and went no where falls on it's face got up to 30mph n said **** it

 

Is it misfiring? Check desired vs actual on your hpop. Low pressure makes all the injectors" weak" and low on power.you may have leaky o ring on injector, bad pump, etc

 

idk if id say its misfiring but its not idling normal and floored it and it took forever to get up to 30mph and the plug to injector #2 was nroken so i prob messed something up in there when i was trying to fix it idk if i broke the insilation on the wire or wat or if the pins are messed up but ill look into it thres also quite a oil leak on passenger side so any tips on where that may have come from while i had t apart would be helpfl too
