Engine shuts down periodicly while driving - 1999 Oldsmobile Silhouette

run fault codes for recorded faults that are giving you these problems. Do not disregard an engine light and continue as it is there to let you know that serious engine/ gear box is about to happen and that can be a costly mistake to make.

Could be the ignition switch, or the low oil cut off , ignition switches do that all the time

May need a new oil pressure switch,it's located next to oil filter,remove electrical connector then part.You may have to remove oil filter to remove part.

Vehicle batteries tend to die during cold weather months since more amperage(power) is required to turn over the engine.

have the sensors on the trans checked this is a common problem

Sounds like an intermittent short in the wire harness or ECU(computer).
If you can locate the computer(in the passenger side kickpanel), try
tapping on it with a plastic handled screwdriver handle, to see if the car
suddenly shuts down? If it does, your computer is shot. Good luck.

most likely the engine is already shut off but because of the speed while it's slowing down there is a rev down period ( no pedal respond )
Check for power loss at the distributer icm most commonly bad

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

give the engine a minute or two to cool down before turning it off. This cool down period allows oil to circulate and cool down the bearings in the turbo. If you shut off the engine immediately after hard driving, the oil can gum up around the hot bearings and create problems down the road.
Hope this helps

Thanks for using Fixya
Have a nice day!

check fuel filter.
Fuel Filter
The fuel filter should be replaced regularly. Its performance is reduced by dirt and water collected over an extended period of use.
Replace as required.
