Tachometer Issues

[john.urciuoli]

I just purchased a '91 RS 305/auto car. The tachometer never shows lower than 2000 rpm and is usually between 4-6000 when driving around town. Normally with an aftermarket tach, I would say the switch is set to 4 cylinder, but this is the factory in dash tach. Any ideas?

It has 5.13's in it.

read on thirdgen.org..... thats actually a tech site.

is a resistor/cap circuit.. one of the two is failing. probably the shaved resistor chip... theres more info on thirdgen.org

Its the tach.My car does the same thing.I`ve heard it happens alot to the 91/92 RS Z/28s.Just buy an aftermarket tach like I did.

there is a topic in thirdgen.org about this you need to add a resistor to it as the factory resistor burns out if you take apart your gauge cluster behind the tach there is a small board that has a black and white chip on it that is the resistor that fails
mainly from gm being cheap with these cars back then

I know after seeing this I went looking for what else the toothless fuck posted. I was laughing my ass off at the post you made. :D I wish 40 year old guys bragging about paid off trailer homes would stay longer.
