The car: '91 Accord DX, automatic

How do I do it? Is there a screw or something that I will need to turn? If so, which way (my car is showing 68mph REAL as 75mph), where is it, and how much do I turn it?

Thanks in advance!

 

take it to a honda dealer, they can do it.

what happened? speeding ticket I guess?

 

yep, speeding ticket. took it on the highway next to my dad's new car and it was way off. anyway to do it myself? dealer is a bitch moneywise.

 

try local places.. we have one here that does it pretty cheap for the public.. they are busy cause they also do the city cops cars too

 

Is it not possible to do it yourself? I just want to get it ballpark, I'm not looking for down to 1/10mph.
