My cluster all lights come on and gages fluctuate while driving


so what works and what not.
so far we have cluster issues
does car drive, ok day and night.
and all accessories?
did engine stall driving?
did Head lights dim? on, driving?
my guess is the engine stalled or idled below 300rpm
and the ECU went to Key on self test mode, (they all do that)
watch the RPM guage? see that needle, ?
if it goes below 300 rpm that is engine stall.
or worse
This cars cluster is really just a digital display
so if the PCM cant talk to the cluster, the cluster will go nuts.
for freeze.
We use a scan tool to see whats up.
or use the cluster self test covered in the shop manual.
the cluster has 2 fuses that can be cracked/loss or corroded.
the cars battery can go weak.
if the charge/battery light glows, engine RPM good
then the alternator systems is failing
if the volt meter (if opted) in cluster drops below 14v, and engine is still running, the same, alternator system failure
or even a loose belt at the alternator.
if the battery voltage drops too low , all electrics go nuts.
and engine stalls.
what dies first with low battery , is luck of the draw....
so what was battery voltage
and engine RPM at the point of failure.??????????

Every once in a while my check engine lite comes on. When I started my car this morning, I notice the needle for the RPM jumped back and forth for a few seconds, then went to zero. After pulling away...


The problems could be related, or separate.
The first thing to do is have the computer scanned for trouble codes to find out why the check engine light is coming on.
The codes will give you or a mechanic direction as to what to test.

Service engine soon light comes on and then goes off and back on and the rpm tack jumps about a half grand while driving


The Sensors are losing ground on the engine tap into the ground for the sensors and run the new ground back to the engine negative "-" on the battery, that will stop the check engine light from coming on and going off.

Just bought a 97 Aurora and had tires put on front and balanced. Now traction light comes on while driving and RPM goes to 0. After I pull over, it will run fine...What could be the problem?


OK, when the traction light or abs light goes on when driving then it could be a bad wheel speed sensor or traction control module. IF the RPM goes to 0, that may be an engine sensor problem or wiring to the sensor for the crankshaft position sensor or cam sensor.

I will be driving down the road about 65 mph and all of a sudden my truck will just sputter and then have hardly any power with rpm needle jumping from 1000 to 1500...cannot go over 30 mph. If i stop and...


Sounds like a fuel problem. I'd start by changing the fuel filter and running a can of Sea Foam Engine Treatment through the engine. With at least half a tank of gas dump half the Sea Foam in the gas tank and the other half in the crank case.
If this doesn't fix it check the fuel pump, don't just decide to change it or have it changed they can be rather expensive (depending on engine and model).
If the fuel pumps checks good and it's still happening you'll have to start looking into distributor or timing chain problems (usually not intermittent).
