My 2k3 SE rear springs bottom over speed bumps like nothing I've ever seen (and this is at something like 3 mph). My '95 didn't do this; is everyone else having the same problem? From the threads a while back, I was hoping maybe this had been fixed for 2k3...?

Also, anyone else getting a rough idle? I think it may just be bad gas, 'cause I haven't noticed it before. But I'm getting a miss randomly every few seconds, and some vibration. According to Nissan, won't the SES light come on if there's anything wrong with the engine that would cause this (ignition coil and/or lead, ECU, idle control valve, etc.)?

Thx!
