Hi Guys
I recently had my NSX battery checked by a battery specialist which indicated after a full charge time
at 58% capacity. The load check on the alternator done at the same time was perfect.
Obviously with that poor battery result the next move was to replace it.
Surprisingly the car now idles really smoothly at around 900rpm whereas before it always used to have a pronounced hunt
at idle - continually oscillating between 600 and 1200 rpm - especially when cold.
I have previously disconnected the old battery for recharging a couple of times as well as removing
the clock fuse to reset the ECU and these resets have never improved the idle so I can't see that the ECU reset figures in this.
So interested to know if anyone can explain why simply replacing a battery could have this result.
Cheers John
