Revs jumping after WOT in 1st gear

vendredi 13 février 2015

So the story goes, The other day I noticed when I started my car, a bunch of dash lights would come on (ABS, TCS, Brake, Battery, Power Steering, etc.) as well as the power steering not working. A free diagnosis proved that the alternator was dead so I just replaced my alternator, and when I started the car, everything was running fine, the battery was charging, and all seemed well. I let the car warm up and charge the battery a little bit, and decided to take it for a drive. I was easy on it for a good 15 minutes, but then decided to open it up in first gear. I revved up to around 8k or so, and pushed in the clutch so I could coast to a stop. As soon as I pushed in the clutch and let go of the gas, the engine revved itself all the way to redline, but fell down to about 3k RPM where it sat and jumped up and down by itself (was not idling). When I tried to push the gas, nothing happened. It did not respond to the gas pedal. I eventually coasted to the side of the road and cut the ignition. After I cut the gas off, I tried to start the car again, but it wouldn't turn over (edit: the starter would spin, but the engine would not ignite). The battery had plenty of charge to start it, so that is not the issue. As soon as it started revving itself, I got a CEL. Haven't had a chance to get the code read yet. I posted a video here (note that the TCS light is only on because this was the first driving cycle after reinstalling the battery):
