i was wondering if the gauges on a 92 mustang 5.0 lx are accurate? the tach reads 4000 just idleing and the temp gauge may seem a little off. anyone else with these problems? and would the fix be going to aftermarket gauges?

ok thanks, i was actually looking over old service records because i just bought the car about 3 weeks ago and it says the tach is innaccurate, so ill be replacing that. the green wire on the aftermarket tach goes to the distribuator right?

There is a voltage limiter/instrument voltage regulator on the back of the gauge cluster that allows for some calibration adjustment if your gauges are not reading correctly.
However it sounds like your tach is toast. :(

Depends on how much money you want to spend.
A whole cluster is going to be expensive.
You can get the speedo and tach in 3 3/8" and the others in 2 1/16" to fit the factory cluster though if you want to do them one at a time.
