Car Forum / Oldsmobile Cars / March 200591' Olds Ninety Eight
The problem that I have, and I have had this problem since I purchased the car 3 years ago so I have learned to live with it, is that I lose power in certain instances. When the Gas Tank gets below 1/4 of a tank I sometimes lose acceleration power for just a few seconds. Since I pretty much take the same route all the time, it always happens in the same place. When I am on the entrance ramp to the highway. The ramp is a curving incline, and when I approach the top of the incline, I lose acceleration power, and it normally returns after about 5 seconds. This will also sometimes happen when I get real low..... like 1/8 of a tank and then it will happen just about anywhere. In that case I generally pull over, turn off the engine and wait for a few minutes, then start it again and pray that I make it to the next gas station. If anyone could give me a clue as to what this might be, and how expensive it would be to fix. One fairly quick and inexpensive step would be to put on a new fuel filter. No guarantees that this would solve the problem. but it's worth a shot unless you've already done that. > The problem that I have, and I have had this problem since I purchased the > car 3 years ago so I have learned to live with it, is that I lose power in [quoted text clipped - 9 lines] > the next gas station.

The fuel pump is getting starved! A good rule of thumb is a min of a 1/4 tank of gas with fuel injection. You can get by with less if its all basically straight driving..interstate for example. > The problem that I have, and I have had this problem since I purchased the > car 3 years ago so I have learned to live with it, is that I lose power in [quoted text clipped - 9 lines] > the next gas station.

I have a 1992 model (exact same car) that does the exact same thing. I took it into my mechanics shop, as replacing the fuel filter did nothing to fix the problem and that is about as far as I trust myself with this kind of problem. Evidently it is the input nozzle on the fuel pump. These things either clog or loosen over time and when you change fuel levels drastically (like rounding a 360 degree exit ramp) and when that happens you have a momentary loss of fuel to the engine. Mine does it all the time. The problem with fixing the pump is that it is _not_ cheap. The pump is inside the gas tank (as with almost all newer cars) is inside the gas tank. Fixing this problem requires draining, dropping and dismantling the tank to reach the pump. The part or parts required to fix it are quite cheap, but this can run into hours of labor. $$$$$$ My mechanics advice and the advice of everyone I know that knows anything about the car is simply this: At some point (my car has 253K on it and it hasn't happened yet) the fuel pump will FAIL completely. When that happens, THEN address the problem. For now, just keep a half-tank of gas in the car at all times. That is my temporary solution (for the last 100,000 miles) and it works everytime! Hope this helps. BigBob |
