Any ideas for Glitchy gages?
Thanks again for all the previous help everyone. My 87 Iroc is taking shape!
Now on to the next project - Gages!
Fuel Gage is typical GM - it works occasionally
Speedo floats about +/- 10mph
Tac also floats about +/- 500 rpm
Amp Gage is dead
Temp Gage appears to work but even with a new 190 degree stat, it hangs around 160 degrees when driving.
So my question is - should I be looking at sending units or the gages themselves?

Likely the wiring in between for corroded connections. Amp gauge, did you check it's fuse? There is a cluster pin out post from an 88 hanging around. Check and see if it is useful for you.
