Pull the error code using a paper-clip. Instructions for retrieving error codes and interpreting them are on this site.
You want to figure this out before messing with other things in a quest for more power. It needs to be running correctly first.

Re: check engine light/valve rattle
use a paper clip to jumper the aldl pins a to b . this will put the ecm in diagnostic mode and the check engine light will blink the codes.

A paperclip is used as a jumper wire.
When I say " instructions can be found on this site ", it's a hint to use the search feature to find the instructions, as they are already written out for everyone to use.
People here don't mind helping others, but you are expected to do some reading. After all, it's your car.
