VX Revolutions

[Pepino]

no starnge sounds at all and no check engine light it even feels smoother and quieter i can go really fast and not notice because of the quietness lol and i dont have anything heavy on my VXand ya thats how my VX usually is the first one is always on as soon as i pass 20 mph but if im going slower than that its off

I agree with Eric. Start with the fuel filter & run a bottle of fuel injector cleaner every month or two. If that doesn't fix it then maybe start thinking about the fuel pressure regulator. The symptoms sound like your Mass Airflow Sensor but that would be throwing a code.

You may not be getting enough juice to the motor - have your battery and alternator checked. The engine should run off the alternator once started but there's still a trickle when you let off the engine, like at idle when the voltage drops - at that point it's relying more on the stored energy of the battery - if you have a bad cell it can cause the engine to power down and you end up losing it at the plugs - when accelerating you have more available amps at the alternator so you don't see the power loss. Have you had any issues starting? Just some suggestions.
