Which code are you getting? The list of what each code means is in the FAQ.... http://www.3geez.com/showthread.php?s=&threadid=185

Most likely the EACV (electronic air control valve). Common thing on EFI 3geez

Try your ignition module. My brothers tach bounced all over the place and I replaced his ignition coil, cap, and ignition module. And that took car of his tach.
