Fuel System Issues?

[evillecutter]

replacing fuel pressure regulator, idle control valve, and throttle position sensor fixed this problem for me (i also replaced my spark plugs and fuel filter at that same time) - no idea which one was actually the culprit but they all work together anyways as well as being fairly inexpensive and extremely easy to replace - or it could be intake manifold gasket leaking

Some good thoughts there.

Perhaps this is related: I've also noticed that when off-roading my air filter gets filled with dust quickly here in TX leading to the Vx losing power / dying / not starting until the air filter is blown out or changed.

Thoughts?
