20 Most Recent 1995 Oldsmobile Ninety Eight Regency - Page 3 Questions & Answers

Hello Vicky.
When I see this happen to those models it is usually a crankshaft position sensor that is getting hot and going open circuit.
When it cools it makes contact again and starts up.
While the issue may be something else like an ignition module the most common by far is the crank sensor.
An experienced technician with proper equipment should be able to determine the problem easily if he can get the car to quit.
I hope this helps your find your problem.
Thank you for using FixYa.

there is a small set screw in the base of the mirror you will need to loosen this and then slide the metal plate out.

The starter is near the bottom rear of the engine. Just follow the large (red) cable from the battery.

FIRST SCAN CAR TO SEE IF COOLANT TEMPERATURE SENSOR IS WORKING SEE IF YOU GETTING ECTS CODES. IF NOT CHECK THE COOLING FAN FUSE AND RELAY.IF BOTH GOOD HOTWIRE THE COOLING FAN USING JUMPER WIRES TO CAR BATTERY.IF FAN DONT WORK REPLACE THE COOLING FAN MOTOR ITS FAULTY.

que bien Gotita nice name you will find 2 of them Fuse boxes that is 1 located in the motor compartment the other inthe dash or rather under dash should be on drivers side

You hook it to the same connector for the engine controls

I would check the fuses to be sure no issue there, then... I would check the blower resistors next. This should be a module very near or mounted to the blower motor.

you may have a faulty temp, switch replace unit

Replace plugs and wires at the same time.

you have 2 sensors 1 goes to the computer and one to the gauge at the part store tell them you need the gauge sensor not pcm sensor.

Hello walt_herd,

Thank you for choosing fixya.com.

Most vehicles have two O2 sensors; 1. behind the engine the exhaust manifold pipe before the catalytic converter; 2. just past the catalytic converter. The first one may be accessible from above the engine, if not, securely raise the vehicle and get it from underneath. The second should be accessible (if equipped) from underneath. The electrical connection my be inserted into the floorboard of the car (with a small screwdriver, pry the rubber piece off,and pull the connector out. Disconnect, take out sensor; reverse process for new installation. The first sensor connection may be clipped to a bracket or the block on the back side of the engine. Disconnect the connection, and take out the sensor. Reverse process for new intallation.

While it's possible to remove these with an opened end wrench, it's easier if you purchase an O2 sensor socket. It has a cut down the slide so you can get the socket onto the sensor, that the wiring will slide into. Each make and model socket size may differ.

I hope this information is useful and helps you get your O2 sensor(s) replaced successfully.

The power steering pump/reservoir is down below the pass. side of the engine, right up against the firewall. Will have to reach down between firewall and 2 heater hoses to get to the cap.-

It is a mute point because you can't do this yourself. Your system has air in it plus moisture. All that need sucking out with a refrigerant gas recovery machine to create a very strong vacuum, then the system is checked for leaks. Only then is the refrigerant gas installed by weight. Freon is the brand name for a gas that is no longer used. There is a sticker in the engine bay that tells you the weight of gas and the amount of oil. This explains, take it to a shop that does AC. https://www.fixya.com/cars/r29878326-recharging_vehicle_air_conditioner ..

The blower resistor may be going bad and need replacing. Does it do it only on one or any fan speed? I'm not sure where that particular part is located for it has been number of years I have looked at vehicles older than 18 yrs. but I hope this steers you in the right direction. Jesus loves you, John 3:16-17 (KJV)

I think you could use this manual method instead.. My nephew used it to repair my car and it's totally perfectly fine now. Here's the website he bought it from. www.reliable-store.com

GM doesn't believe in making things easy. No access panel

How do you know it's surging? In any case, about the only thing that can cause this is a faulty regulator in the alternator, or a poor wiring connection (e.g. battery cable or at alternator).

Have you checked the vacuum line with a gauge? If so, how many pascal units does the vacuum line read? Vacuum gauges are around $5. Furthermore, I believe the design is sealed vacuum only system. The solenoid could be bad, but to my knowledge it is not an electrical component. A split in one of the vacuum lines could be cause of your problem. You would have to trace the all the vacuum lines back to the source to find the problem. You would need that gauge to detect a leak in the system. Could also replace all the vacuum lines on principle since the vehicle is going on two decades.
