What makes the car start and run but gauges go off and key light comes on


The first part is magic, (EFI system and good engine)
but?????
gauges go off can be a bad fuse or loose fuse to cluster.
when any Gas engine stalls. the RPM drops to 0
the EFI sees that and goes to key on, not started self test.
this is covered in the operator guide.
key light comes on KEY LIGHT, HUMMMMMMM
Let me look at the waring lamps, there are many.
one light is engine overheat that is logo of a thermometer but looks
just like a key.
http://dashboardsymbols.com/the-symbols/
is this a engine stall post
or engine runs perfect all the time , but only my dash acts funny
you didnt say?

key lamp?
immoblilzer (big trouble there)

a stall is anytime engine RPM drops to zero. called a STALL.
if your cars engine stalls, post that way, the lamps are all normal
on at any stall, on any car.
at a stall , rpm goes to zero and MPH drops to zero as you coast to a stop , stalled. that is all normal for any stall.

if engine stalls.
that is complex.
here is list.
  1. lost 12vdc power to EFI system. (battery died, fuse blown)
  2. never gave your car the 60,000 mile tune up, see opr, guide.
  3. bad fuel.
  4. overheated the engine.
  5. engine oil gone, never ever checked at each fill up.
  6. other more complex EFI system parts failures, ASK.

Car stalls, will usually restart after sitting a while


Seeing as how you had a check light on,
what codes were present & did you diagnose
& repair them ?

Sounds like a bad fuel pump on the stalling or
no start

Is the check engine light on ?
It sounds like the engine temp sensor is not right, but if that were true you should have a check engine light and a code for the sensor.
Have you checked fuel pressure ?

Engine will not stay idling


Dirty throttle plates and idle speed control motor can cause stalling without setting check engine light. If your check engine light is on you will have to get the code out and continue from there. Vacuum leaks will also cause engine to stall but usley set check engine light.

Check engine light/engine stalling, related?


GET AN AUTOPARTS STORE TO READ THE CHECK ENGINE LIGHT CODE. OXYGEN SENSORS ARE COMMON CAUSES. DON'T SEND RAW GAS INTO THE CATALYTIC CONVERTER. IT WILL BE COSTLY TO REPLACE.

97 olds 88 check engine light on car stalls periodically


when you say stalls, do you mean shut off of just get low on power?

my check engine light comes on and then oil press light come on and the car shuts off but the lights and music stayed on.
if its that the car needs oil and shuts down to protect itself but it will turn on minutes later.

if stalls periodically, shows check engine light and the car looses a bit of power, in the engine, :

1. your coolant may be having problems getting to the engine in the way it was met to get to the engine

2. the belt might be a bit off and that could be why you get the slipping feeling

3. your exhaust may be a bit clogged. or your engine may need cleaning

i had both problems my car shut off and my engine was slipping. my EXPENSIVE but great machanic found out it was my oil level and my coolant was rusty and not getting to the engine. now she drives like the original 97 olds 88

Engine stalls, check engine light, not fuel filter.


the white smoke as it stalls could be steam in the exhaust. This is caused by coolant leaking into cylinders from a leaking head gasket. You should check cylinder compression next with a compression tester.
