You may get a better response by including your basic question in the title instead of just "HELLLLLPPP!!!" Something like "Code 16 and bad idle".

Some punctuation wouldn't hurt either.

Anyway, the ECU will set a code 16 when there is a break in the electrical circuit for the fuel injector system. Check all your injector clips, wire harness, and any other connectors for loose or damaged connections.

Another cause is the main relay.(A search will turn up a wealth of information about it) It provides power to the injectors. Another possibility is a bad injector coil. Check the cheap and easy fixes first before you start throwing parts at it.
