Iv posted this b4 but i didnt get any replies so imma repost... does anyone know why i wouldnt have any power past 3500 rpm? If i were to floor it from a dead stop it would go up fine until 3500 then go up very slowly... i changed-tps,iac,crank postioning,camshaft positioning,plugs,wires,and brand new coil, even swapped diff computer still nuttin...

 

does it do this both in nutral and in gear? is your fuel pressure good and have you checked your compression
