check engine light on hELP!

I just installed some OBX spark plug wires which a friend gave to me. I was driving around fine but today the check engine light comes on. Im guessing it has something to do with the wires but im not sure what. I reinstalled the stock spark plug wires but the light remains on. Any ideas?

find out what code it is!

how do you check the code?

If your car seems to be running ok, disconnect the negative battery cable for a minute or so. Reconnect, then start engine & check for light.

OBDII scanner is needed to retrieve codes

An obd2 scanner is not needed to pull your codes...on the 99-00 civics (not sure if it's different than yours) there is a plug underneath the passenger glove box that has two wire going into it. It isn't really plugged into anything. Take a piece of wire and put it in both sides of the plug. Turn your engine to run and the engine light will blink, I believe a long flash is 10 and a short is 1 (ex 2 long and 3 short would be 23). It will keep repeating all the codes that have been tripped. You can look up the codes in a chilton manual...I'm sure you can find it on the net too.

Hope this helps...it has always saved me a lot of time.
