Check Engine Light came on this morning! Cause Cylinder 1 misfire. Plug looks bad. Should we start with just changing out plugs ... or go right away to wires and coils too ? What else could cause the misfire?????

 

Change the spark plugs with stock Champion copper plugs...no platinums or split-fires!

 

Stock plug is usually good, if you'd like you can goto toher plugs such as Autolite or NGK without much issue. Just get stock replacements. Now the real question is how'd it look bad? What was wrong. Sooty, Oily, Mechanical damage, just worn the heck out?????
