'92 Speedo Recalibration
Replaced instrument cluster with a rebuild a few years ago. This corrected all my fluctuating oil pressure, fuel gauge, etc. but..........
Before the replacement my idle showed about 750 rpm. After replacement idle showed about 1,000 rpm. A Tech II confirms I AM idling at 750 rpm.
Is there some adjustment/calibration screw on the cluster that will enable me to adjust the rpm back down to its actual 750 rpm?

Did you get the right cluster..? Year - Style?
Because sometimes they are set to read voltage differantly..
So maybe you got the wrong one?
Other then that I believe there isnt a way to set this.

Sounds dumb, but ....
I had the same problem with mine ...To fix it, I pulled the clear lens off the instrument panel, and popped off/reset the needle to point exactly at '0' with the key on, engine NOT running. Just be careful, as there is a small clear paddle on the opposite side of the pointer shaft from the pointer arm, and the engine has to be stopped in order to be able to pull it out of the panel (the paddle fits through a notch in the panel itself). Since then, it hasn't been an issue, and it appears to be staying accurate now .... Some may frown on this idea, but it worked in my case. Just my .02 ....

Thank you for the responses Ruskybear, Gearhedd, and ACG!
Hey ACG, sounds like my kind of "jury-rigging".
Can't remember- can I get the clear lens off w/o total removal of the cluster assy?
How difficult was it to pull the needle off? What tool did you use?
Explain this comment again, please "a small clear paddle on the opposite side of the pointer shaft from the pointer arm". Do you mean the clear paddle is on the inside of the instrument cover plate, while the pointer is on the "outside"?

Going L to R on the Panel -
Tachometer - 0 RPM (Key on, engine OFF)
Speedometer - About 60 - 65 MPH (I set mine while driving smooth and level road with
the HUD/cruise on, took SEVERAL tries !!!!)
Fuel Gauge - Empty (Key on, tank empty, or key off) I set mine to the top of the orange
area when my "check gauges - fuel warning" first came on, but you
have to remove it with the key off(it sits at Empty), and
guesstimate how much to move it. Might not be worth messing
with.
Temperature - 100 (Key on, Engine COLD)
Oil pressure - 0 (Key on, Engine OFF)
Boost - 0 (Key on, Engine OFF)
Hope this helps some, let me know how it goes....
