Since I only get 19 mpg I m going to replace the sparks plug which look.bad anyway .

FL58,
Curious: How do you know yer spark plugs look bad- what objective measure do you use?

Google ...park plug chart ..
In my case no chart needed lots of corrosion ....

Corrosion ? I assume you are speaking of that greenish crap found on metal when exposed to water and air.
What, do you live and live at the bottom of some seashore?
Seriously, please describe what you see around the spark plug electrode, I'd like to know what corrosion looks like. I may be needing an update on the colors of corrosive spark plugs...
