1998 GMC Jimmy Erratic Tachometer

My 1998 GMC Jimmy SLT Tachometer just started going erratic. After a bit it settles down but then might drop to zero RPM's and then goes erratic before functioning normally again. It's as if the cable is sticky. Any thoughts?

SOURCE: 95 honda accord v6 tach

Hi ....
On your HOnda accord V6.
The rpm is generated from the Distributor.
The more possible problem for erratic RPM is the cam sensor inside of the Distributor. But I guess you can't buy just the sensor.
And can afect the engine performance.

OK. I hope this information work for you.
I work on cars everyday. Thank you for use fixya.

SOURCE: 2004 stratus 2.7L Erratic idle, sometimes dies, sometimes revs at stops

No its not the idle control valve. In 2004 dodge had a spark plug and wire problem. They did make a new one but did not classify it as a recall so just go to your dodge dealer and ask for the update

SOURCE: gmc Envoy with erratic fuel gauge.

I have found that just about 100% of the time this condition is caused by a defective fuel gauge sending unit in the gas tank.

Transmission hard shifting between first an second gear only when this happens the tachometer goes erratic


You have a engine RPM sensor that is not working correctly. Computer thinks you have push gas pedal to the floor and is providing that type of shift. It may be the sensor attached to your gas pedal has worn out.

Our 2006 GMC Envoy's gas gauge started going up and down the last time we filled the tank. After driving for a while, it settled down and did fine. However, tonight when we filled it with gas, it started...


{: ) It is still safe to drive as long as you are aware you have enough gas for the trip. The problem is your fuel level sensor could be getting erratic and sending inaccurate signals to the engine control module, thus illuminating the check engine light at times. If you unexpectedly run out of fuel, thats when you will stall on the road. Better have it checked as soon as possible.

Could the mass air flow sensor cause 98 Jimmy to not start? It only turns over and begins to start but boggs out.


Yes it could cause it not to start or could start and run very rough. Are you sure you are getting proper fuel pressure? Could be many things that would cause it not to start and run though. Is your service engine soon light on the dashboard lit up? it is where your gauges are.

4 wd low range will sometimes engage 4wd high will never engage


I had a very similar problem with my 98 gmc 2500. The 4 low would engage - though the upshifts were erratic, but no 4 high though the light sometimes came on. I changed out the electric shift solenoid or whatever it is called, on the transfer case and it worked fine after that. A fairly simple fix that can be done in 15 minutes. Hope this helps.
