350 EFI idles 200 RPM to high?

[W6KF]

I have a 350 efi, idles at 800 not 600 like
the engine cover says it should.
Replaced the IAC and the TPS. Still
idles faster than it should.

welcome aboard

check to make sure the throttle cable isnt mis-adjusted and holding the throttle open.

also, the idle speed is in gear while in the water. is that when you are checking it?
