Factory oil pressure gauge
Tengo un ranger de 94.
Now that my Spanish is depleted. My factory oil pressure gauge reads erratic when the engine is warm and at idle only. It is erratic in that it goes way past low, far enough that it points up and hits the top of the cluster. It does this on the high side in a random fashion but very quickly. As soon as I am above idle it goes back to normal.
Any ideas where to start? Also where is the sender for the gauge?
