My 93 sc 5spd sound fine at idle when I rev it up it seems fine, but when I try driving it, it studders and barely moves. had the same problem last summer, a repair shop said it was the o2 sensor on one side(the wires touched the header and got a little melted) I wasn't sure if an o2 sensor can mess up the car that much, replaced the sensor, seemed fine (a felt a little studder once or twice, but ignored it) they told me the other one was fine. now its doing it again, should I replace the other one, or doy you think it might be the coil pack or other ignition probems(ignition is original with the exception of the wires).
