basicly dark - black - spark plugs are from too rich mixture but how fast are we taking here?

how long does it take to turn them black??

2 days is way too short period... you defenatly got rich mixture.

check for clogged air filter
check your dirty injectors
check forweak fuel pump
check for faultyO2 sensor
check your leaky vacuum lines
check for dirty idling speed sensor and throttle body

check those parts then get back to us with the feed back... i am not really sure which part is the one responsble for your problems so you have to check them all.

P.S: can you post a pic of them spark plugs so we can see how "dark" we are talking about here??
