    Got an annoying problem

    OK for a couple months now I've had this issue that is very annoying, if I set the idle to normal it will idle but if I tap the throttle it will slowly die down, and other times it will slowly die down without tapping the throttle, and other times very rarely it will be fine. I have a volley black fuel pump and flowing a fuel pressure 13-15 psi when this is happening. Any suggestions?? This is getting very aggravating to deal with

    I have a hand throttle which I adjust before it dies out but that just pulls the idle up higher, if I forget to push that lever back in when I'm driving the motor will ramp up between shifts and that's aggravating and kinda embarrassing. Think my idle is too low?

    When I stop at a red light light the motor will slowly die down if I don't pull my high idle switch or rev it a little, I always have a constant fuel pressure of 13-15

    Sounds like maybe an air fuel mixture.

    You might try replacing the fuel filter to see if that helps.

    I changed the fuel filter and air filter. I've checked for leaks and seepages I can't find any, think my idle could just be set too low?
