If you removed the the cat, then yes you are going to get a check engine light. Dont worry though, its just an emissions code.

you have to buy a spark plug non fouler. makes the sensor stick out of the exhaust a little further so it reads less o2

take your negative battery cable off and press your brakes for ten seconds and hook it up again

voila it's gone
