this is about the 3rd time someone metion the fuel filter,I will change it, my thought was if it's the filter,it would starve for gas at higher rpms more so then low rpms like this one does,I will also try the spraying wires things,I'll have to block the tires,chain it down,set the foot brake,cause it will be the wifey behind the wheel giving it a little gas,I didn't mention we just spend about 600 miles together and the temtation might be there
