RPM is stuck.
 

my rpm gauge is stuck, like resting on the bottom. i know its not stuck becuase i hit a bump yesterday and it started working fine, but then it jumped to the right again and stayed resting on the bottom.

before i go taking my consol off i wanted to see if there was anywhere else i should look, dizzy? what could cause this to happen?
i need to fix it to pass smog... and well to just have it fixed.

91 lx 5speed.

RE: RPM is stuck.
 

ive searched and that has provided no help. anyone?

RE: RPM is stuck.
 

sorry to ask this but why do you need a tack to pass smog I live in a state that dosen't have smog test so it is kind of intresting to me

umm it prob lose on the back

RE: RPM is stuck.
 

the wiring? i know theres atleast 2 wiring harness plugs that go into the back, and the speedo cable.

im not sure, i know i saw on the smog test sheet they measure how much O2 and CO2 there is at 15mph and 25mph, and for each they measure your rpms... dont know.

RE: RPM is stuck.
 

They measure it on the dyno, I'm pretty sure. Not using the tachometer. They're not really that accurate anyway.

luckely i called ahead because i wasnt sure, but they did say it would fail. could just wasted 57$ for a dumb fail.


any other places i can take a look before i tear the dash off?

also... since there is no tilt wheel, how is the process of removing it? my prev mustang had tilt wheel so it was pretty easy..

dude, get a wiring diagram for it... and just trace the wires... if it worked for a short time because of a bump, that means some connection isnt tight, really could be any of the wiring...

or... what i really suggest... go to autozone, and spend 100 bucks on an autometer tach and call it a day.... ****s gonna be more accurate then stock....
