Re: [DML] Rough idle and hard starting.

A little black appearance can be normal on the spark plug. But a 
better description is needed to really diagnose any problems you may 
or may not have. Follow the following link to see which picture 
matches the appearance of your sparkplugs the best.

Idle fluctuation is totally different then a rough idle. A rough idle 
in my car was when the entire car shook and rocked back and forth.

To determine any problems, describe both the hard starting, and any 
accelleration problems you have.
