it looks like my tach is reading about 2X what it should be, i've read some of the previous threads talking about people having similar problems, but i couldn't find a good solution. Does anybody know for sure??

 

the problem is the stock tach sucks, and as it ages, it gets worse.

 

My tach does the same thing. I'm working on a fix ... hopefully I'll have one soon. Wake up this thread in a few weeks and I should have the fix by then and post results.

anybody have any updates????

 

Sorry bud, give me a few more weeks.

 

i had a similiar problem. the magnet must go bad in there or whatever. i just wired a aftermarket one in. was pretty easy didnt take very long. it was laughable to see how badly off it actualy is sometimes.

 

Seems like I read on here somewhere that a capacitor goes bad on the back of the cluster.... I think it even had a pic. There it is.... https://www.thirdgen.org/techbb2/sho...hreadid=233157
Oh yea, I pulled my radiator, cleaned the fins out, replaced the thermostat because it was running hot. Afterwards I did some datalogging only to find out that the factory temp gauge shows 20* high. Guess that could be my temp sender, though.
