hi just finished up the egr delete on my 6.0 after letting it rund adn driving it a little checking oil and coolent leves bolts and everything is ok. it starts up idles funny lumpy or lopey but when it kicks into high idle because its cold it sounds fine. but when normal idle sounds like a camed gasser. then when i put it into reverse or drive it truck shakes and feels like its missing adn shaking jerking motion but once i reach good speed or hammer down it doesnt. if where you plug into the injectors is broken and it may be missfireing will it throw a code? i have no code showing up. we are going to run a cylender ballance test. and see what comes up. any info would help i have to drive to california in 4 days.. will this hurt?
