Engine Code - Cylinder 4 Missfire

[slowford]

The check engine light came on in my 1996 Mustang GT. I used a OBDII code reader and found the offending code was for "Cylinder 4 Misfire Detected." I was thinking of changing the spark plugs and wires. I have only had the car a few months and I am not sure if they have ever been replaced (113k miles on the car). I read the coil packs should never need to be replaced, so I was thinking that I wouldn't need to replace them. But I figure that new plugs and wires couldn't hurt (except for my wallet).

What your guys thoughts? Is replacing the plugs and wires a possible fix for a misfire? Are they any plugs and/wires you all would recommend for a stock 4.6 motor? Thanks.

i'd go for some Autolite 764s. you might as well replace them to be safe. you should consider upgrading to 9mm spark plug wires as well.

heres a list of spark plugs for the modular 4.6L. it will help a lot:

Change the Wires and Plugs... Look into Accel Spark Plugs, or maybe Boch Dual Platinum Plugs, and yea 9mm wires...That should do the job.
