well it was the egr before and its been disconnected lately just so it would run right. well when i went to crank my truck today it wouldnt run right at all and mis fired worse than it used to. i had no choice but to hook the egj back up, that truck jerks so bad going down the road i couldnt stand it. i scanned my codes and it showed my egr was diconnected (duh) but it also said misfire on cylinder number 4. so im guessing ill but a new egr and get plugs and wires. idk what else i can do.
