Yes. CEL comes on indicating that the speed sensor is unplugged. I just couldn't get that cable to fit in the transmission right, so I left it unplugged. Also, my ecu was flashing map sensor a couple days ago, but shouldn't be flashing anymore. Would either of those codes cause the car to redline earlier?
