RPM Gauge screwed up

MX-3 Money · Post by **MX-3 Money** » June 30th, 2006, 1:00 pm

When I turn the key to the on position the rpm needle moves to about 250 rpms and when I'm driving the car around the rpm's are about 500-700 higer then they should be. Anyone had this problem, maybe its my rpm gaguge and i should replace it?

Do you mean it moves to 250 WITHOUT the engine running?

Ya, it happens when the key is just turned to the on position. The engine isn't running.

The distributor has 2 connectors - unplug the 3 wire connector and turn the key to on position. If the gauge shows zero then maybe the disty is going bye bye. If the gauge is still screwed up - then its either the gauge itself or the wiring from the disty to the gauge.

well it happened after i was replacing my glow gauges so i don't think its the disty, plus i just replaced it last summer.

You have your work cut out then - In the future it will be much beneficial if all necessary & critical information is presented first while asking the question.

it's not hard to swap in a new rpm gauge, done both the speedo and fuel gauge.
