I am noticing my car hesitating at around 5000rpm. Not bogging really, it just feels like it flattens out for a sec right around the 5k mark. I installed Steeda U/D pulley's last week and that’s about when I started noticing it. I was thinking it was possibly a charge issue, but my volts stay high. Do the 99/01's have a knock sensor? If so, could a bad crank pulley/dampener trigger it? Any input would be greatly appreciated.
