How crucial are these steps? When i put my new exhaust on the other day i disconnected my battery (was off for a few hours) and for the first 50-100kms it did the usual idle fluctuation every time i went into neutral or put the clutch in. Do these fluctuations DEFINITELY mean that the ecu has been reset without the above steps?
