Hi, I have 2003 accord. I had to take out the speedometer to put blue sheet behind the gauge. By accident I touched the "rpm needle" and it moved. Now when i connected the speedometer back again, the "rpm needle" is acting weird. When the car is OFF the needle is below "0" instead of being at "0". When I start the car it goes to "0" instead of being at 0.78 "idle position".
I tried to fix it by moving the needle back to "0" with my finger, but after a while it goes back to below "0". I was wondering if there is any way to reset the "rpm needle" so it goes back to usual. Meaning at "0" when the car is off and 0.78 in idle position.
Thanks
