I have 2002 350 MPI Horizon motors.
What controls the idle on these motors?
There is no IAC valve on these motors I only see MAP sensors.
Reason why i ask is that the starboard motor is making a loud hissing sound out of the throttle body at an idle.
Port motor does not.
I'm thinking possibly a bad PCV valve.
It's the only vacuum source connected to the throttle body.
