SOURCE: My 2003 GMC Envoy tachometer is reading 5-7000 rpm

I see this a lot on the 03-06 Envoy instrument clusters, it's caused by failing stepper motors on the cluster's circuit board. It can be fixed though, check out this page about how to get it fixed - Envoy tachometer not working

My Sonoma 4.3 v6 is having some issues the rpm gauge is jumping at any giving time besides idling would you know why and I couldn't run dynastics


tachos get their signal from the coil or the ignition control module or ECM
check for ;loose / broken wires in the harness or at connections
There will be no fault codes for tachs unless it affects an adjacent sensor
could be a faulty tacho unit (tacho--tachometer--rev gauge --rpm indicator )

Tachometer stepper motor on the back of the cluster probably needs to be replaced.
Rough Idle can be caused by many thing, but the #1 thing that causes that is a dirty throttle body. Needs to be cleaned with the battery disconnected.

2005 gran am Pontiac 3.4 v6 the car is idling on 5000 rpm I replaced the throttle housing gasket and throttle positioning sensor still nothing idling at 5000rpm still does anybody have and suggestions...


500 RPM or 5000? Reason I ask is the rev limiter shouldn't let it rev over 3500 in park or neutral? If idling at 500 then get an external tachometer and connect it to determine that your gauge isn't faulty! if at 5000 RPM it could be a stuck tps or possibly debris in the throttle body or a vacuum leak causing the idle to increase? Is it idling high or low compared to before it became faulty?

How do you hook up tachometer to adjust idle speed


Use a optical tachometer on RPM. Mark the camshaft with white paint or a optical sticker and shine the meter on the mark. Or connect a CT clamp to one on the spark plug leads and take the reading.

Common knowledge of the road speed, mine hasn't worked for 3yrs and for some reason haven't got a ticket since. Install a tachometer.

the dash voltage egulator probably went bad. First,check the battery & make sure you have 12 volts,not running. Check it again running & you should see about 14.5 volts. If that's good,I'd replace the guage assembly.
