Black spark plugs?
 

Sup guys just had a question, I want to know y my spark plugs especially the first cylinder is burnt already when I just put them in like a month go. The 1st cylinder the plug is burnt alot worse then the rest of them. How can I prevent this and what is happening??

if its really black your running too rich
causes
incorrect timing ?
wires cap rotor ?
theres some other ones just cant think now
hahas

bad injector in the first cylinder could cause a single cylinder to run rich

running rich most likely, it shouldnt be black that fast check ur injectors, fuel and ignition system does ur enging have high kms?

can you post pictures of your plugs?

will try and get pics, it has about 230,000 on it. but runs mint doesn't burn oil and looks mint.
