My civic identify code is cylinder 4 randomly misfire. Can anybody help me fix this problem.

 

90% of the time its spark plugs
make sure to use NGK
also it might be the wires.

do a tune up..

spark plugs, sp wires, disubtor cap and rotor..

 

I agree completly with previous comments but, it sometimes means you have no/low compression in that cylinder too. Might be time for a compression check. This is a chronic problem in S2000's when they've been run low on oil and the bore gets scored up.
