Does it go compleatly threw the rpm range? My heater grid got stuck on and melted the sm, hose that goes from the intake to the afc, I could go 23mph max! So if you can rev out in gear, just low on power I think that is not the issue. But I do think the arm is not traveling on the plate correctly, or stuck!

Could be a number of things, start out with the basics and work from there. Make sure you're getting good fuel pressure, check the pre-filter and fuel filter.
