I'm throwing no codes. I just did this swap with the lsd tranny. Intermittently now my speedometer will quit working, the needle will just bounce up and down. Seems like though after i let the car cool off then start it back up it works for awhile. Maybe thats just coincidence. But when the needle starts going wild VTEC will engage but no real noticeable power output is shown. Are these symptoms of a bad VSS?
