my 90 supercoupe has a miss when under load!i have new plugs ,wires ,coil pack,dis,computer,harmonic ballancer,crank sensor,fuelpump and filter!does this car have a fuel regulator?if so where?does anyone know why it sputters when i push on the gas to hard,or how i can diagnose the problem?no codes come up when i test it!any info would be helpful!

sounds like it might be a bad 02 sensor. have u ever changed them? if not u might want to check them out. that is just one of the many possibilities that it could be though. just start testing everything.
