I have a 2003 330 magnum, just starting bogging down on the hi end, i can gain about 3/4 throttle when i roll into it,but when i snap into the throttle it just boggs down and dies , it happens sitting in neutral and moving,
has anybody else experienced this or know what the problem is, i sure would appreciate the help

 

air filter, fuel filter clean?

 

yes and yes, carb cleaned also, noticed wetness around rubber intake manifold, wondering if this would be problem,

other things done
fuel pump test(vacumn)
inverted carb test(vacumn)
pilot idle adj. no help since not idle prob.
electrical testing(seems and acts norma)

 

i would clutches would be next, but you say it goes fine when it goes. clutches will make it bog out but usally not in neutral. if it was carb i would guess main jet problem area since you say it idles good and starts off fine. the main jet controlls form 1/4 throttle and up. sorry coudnt give more help.
