Hello, thanks for writing in about your Oldsmobile 98. You need to have the charging system checked to see if the alternator is charging the battery. You may have a blown main fuse if the alternator is proven to be...
Hi! I recommend having a close inspection of the harmonic balancer on the front of the crankshaft. When the rubber that's bonded between the pulley and the hub begins to fail and separate, it starts to move around and can...
Hello. When this happens it means that there is a short in the circuits that go to your dash lights. It could be in the dash board itself, the wiring going to the dash board, or the bulbs that light...
You definitely want to reset the computer when you make a repair like this. Resetting the computer will allow it to check the new component for proper operation and set a Diagnostic Trouble Code if there is still a problem....
This sounds like the cam position sensor is failing. The sensor gets "hot" during your drive, fails, and the engine uses the crankshaft position sensor as a fallback mechanism. This is less precise timing, and results in a rougher-running engine...
These symptoms are typically caused by a failing brake power booster unit, likely a vacuum valve in the booster unit. This fault reduces the brake booster effectiveness, requiring more effort to stop the car. It also leaks air to the...
Hi there, thanks for writing in about your 1994 Oldsmobile 98. To start, I would first visually check to confirm that the coolant level is actually staying at an appropriate level and the problem is really fixed. This can be...
Hey there. It sounds like it is having serious wiring issues. It is quite possible that one or more wires shorted. This is a potentially dangerous situation, and should be inspected immediately before getting back on the road. If you...
Hi there: If the quote you were given includes replacing both the ignition coil and module, then a price between $200 and $300 is a pretty fair estimate. If it's one or the other, then a quote closer to $200...
What you are describing sounds like a failing CV joint. A CV (Constant Velocity) joint is a shaft that connects the transmission to the wheels, essentially transferring the power from the drive train directly to the wheels. The CV joint...
Hi there. A coolant leak can be caused by a cracked radiator, broken coolant line, or damaged water pump and more. The best way to find the leak is to have a professional mobile mechanic come to your location and...
It sounds like what you are describing may be related to a faulty starter relay. The starter relay directs power from the battery to the starter solenoid which then engages the starter when you turn the key. When this is...
Hi Wayne. Thanks for contacting us today. Back in 85, GM V6 motors only had one O2 sensor. It was considered an upstream sensor, which means that it was installed near the center of the exhaust manifold. Downstream sensors were...
The starter enable relay on this vehicle is located under the left side of the instrument cluster above the instrument panel fuse panel. If you take out the left front radio speaker and relay is located under it.
I think more than anything else that the multiple grades of fuel you are using is the primary source of your problem. If you use an unleaded gasoline then use a racing 110 octane leaded gasoline, it creates tons of...
Hi Christian. Thanks for contacting us today. If the beeping noise appears to be coming from inside the cabin, it's possible that there is some sort of electrical short that is activating a warning light indicator. If the noise appears...
Hi Shamar. Thanks for submitting your question today. Although we appreciate the inquiry, it's not exactly the type of advice we offer here at YourMechanic.com. We try to stick to OEM service, maintenance and repair tips for cars, truck and...
Hi Christian. Thanks for writing back to us. I remember your question from the other day, and actually, those warning lights is some vital information that could lead to a clear diagnosis. A warning light is triggered when a vehicle...
If the fuel pump is not momentarily running and priming at key on, then the fuel pump circuit has to be traced to find the power interruption. The recommended service to accomplish that is an electrical circuit/component diagnostic. With regard...
