1994 h22 prelude, smokes alittle, black stuff is shot on the ground out of exhuast, still has original spark plugs and wires, took a plug out and the whole tip was white. what is wrong?

thanks in advance

 

could be just getting rid of carbon

 

running rich

 

Usually a plug that is White at the tip is burning too hot, are the plugs the correct heat range ? Might be time to replace plugs anyway if as you say they are originals.

 

white is lean. not rich.

BTW - you are WAY over due for a tune up. change the plugs and wires.

from a 94?? damn, buy some plugs dude....... and wires FAST

and stop running 87 octane, it may be screwing up your mix/ignition

 

i just got the car, just spent 800 on timing belt/water pump/rotors. and i run nothing less than 92 octane...so what spark plugs should i get? will that take care of my prob
