So my truck idles fine but once u go above 2000 rpm it Boggs down and it's like I have no power it stumbles on its face but as soon as I left off the gas it idles/runs fine... I changed the fuel filter egr(cause I've had the valve for a while) checked all the wires plugs vacuum lines but can't seem to figure it out. Please help guys!!! It's 92 350 149xxx miles tune up not too long ago
