Help I've changed 4 coils w/4 spark plugs now it's worse
 

My hubby changed 4 coils w/new spark plugs which was done easily enough but now it's seems it's missing firing? ??
Help ..4 Beck Arnley Direct Ignition coil

The specific coils used by Honda are Hitachi coils and can be bought at Rockauto.com. See the thread below about that.

However, although I do not have experience with the beck Arnley coils, they seem like a suitable replacement part so I'm surprised you are having issues and I suspect something else might be the culprit. Perhaps a wonky O2 sensor? Have you had any trouble codes aside from the misfiring? Check engine light?

What plugs did he put in it? Brand and model?

He used Denson Platinum PK20TT 4504

I'll check and get back to you..FYI 96000 MILESTONE Fit sport

Get NGK IZFR6K13 spark plugs and that hopefully will fix your issue. I had denso spark plugs in my car and they were about 1mm shorter than the ngk spark plugs.

Side note our cars need iridium spark plugs as a minimum, it's in our car's service manual.
