Just tried that. When I restarted the VX it surges continuosly now. Until I press the accelerator to even it out. When I let off it continues to surge the throttle and then the engine check light comes on and then it levels out the RPMs.

I took out the K&N filter, put the stock one back in, and disconnected the battery again. When I started it back up it repeated the same thing.
