So 2005 accord exl 3.0 had misfire cylinders 1 and 5 ignore issue (gf car) well could no longer ignore idel was getting bad shaky n louder also starting the car had gotten worse like it had to crank 3-5 second before start. I bought all new coils n plugs and installed starting car was same but driving it was jerk n shaky at idel or low speed but if we're steadily accelerating no issues at all but got to steady speed could fell the jerking I knew it was a misfire ran codes number 3 misfire confirmed 2456 pending random misfire she drove about 50 miles ran codes again cylinder 2-3 mis I need help on where should I began I don't want to throw money at it and it not be the solution

I merged your threads, since they are dealing with the same issue.

Can you let us know all the current codes on your car? Do you have a code reader/scanner? If yes, can it read live engine data?
