So im not saying this is symptoms for other things but a while baxk i was trying to diagnose a shifting issue and unplugged the shift interrupter and it did the identical thing its doing now. I was told to try replacing it and di but I had to do some wiring to make it work and thats when it...
I have a 5.7 efi fuel injected mercruiser that idles high when I start it then kills itself. I have checked the iac and it works properly. I recently replaced the shift interrupter but don't know if that has anything to do with it.
