Think I posted this in wrong place, please forgive me.

225 Mercury efi 1999

What would cause throttle to Rev full when started? I recently replaced throttle cable, then sprayed degreaser on engine followed by wd 40. Obviously something sticking but not cable as tried with cable off.

Have been told probably injector stuck but not told how to check it, i barely can work on carburetor models.

Any suggestions more than appreciated.

Check that throttle cable and it’s position again. Won’t be injector related. Presumably the fast idle lever isn’t up, just asking. Good luck.

Well, I first thought of this, but I disconnected the cable I had fixed from the engine and it still revved
