View Full Version : Help timing a 5.7 EFI, throttle body motor

Trying to time a 97' 5.7 EFI, throttle body motor ( Marine Power) . The motor does not use the special timing tool as you can't plug it into the dist. because the port is being used by throttle body. I need to find out how to put the dist. in base timing mode. It may be that I have to use a PC but trying to avoid having to get dealer to come out to the boat. The manual does not cover the throttle body motor only the multi-port and it appears they are timed different. Help would be appreciated....
