Question about 1995 Buick LeSabre

1995 Buick LeSabre hesitating.

1995 Buick LeSabre, 110,000 miles. Purchased from my father-in-law, who bought it new. Wonderful maintenance done over the years. Started chugging, or hesitating, while driving. No check engine light came on. One mechanic said computer code showed a problem with the mass air flow sensor. He replaced it, no change. Installed another new one, no change. Different mechanic said code shows the same problem, but, not fixed. Any ideas?

    95 LeSabre hesitates/chugs when I am barely touching the gas pedal whether moving already or from a start. Happens especially at 40-45 mph when going up a hill. Have changed; plugs, wires, throttle position sensor, fuel filter, EGR valve, AND had the o2 sensor checked, throttle plate cleaned, ran Lucas oil/ STP injector cleaner/ dry gas through tanks of gas. Check engine light comes on occasionally with a variety of codes which all seem to check out ok. Bought car in June of '08 w/ 74K miles. Now has 81K miles. Gas milage in the high 20's but I know it shoud be better from first hand experience(previously owned a 93 and a 98 LeSabre) Help???

95 buick lesabre won't go unless running for awhile

It's possible in this case that the flushing of fluid may have caused more harm than good. If a transmission has never been flushed but only drained and had it's fluid and filter replaced (which only changes a small part of the fluid) there sometimes are tiny bits of metal that work their way into intricate places. Such as internal seals and gears. When a flush is done on a transmission which has never had it priorly done sometimes it can cause an internal leak or gear slippage due to these little bits of metal being removed. The manufacturer of a transmission flushing machine states not to use it on transmissions that have not had it used on them for a regular maintenance service. By regular they mean (for most vehicles) every 50 to 70 thousand km's. That being said if your new but used transmission was not regularly maintained with flushes the flush done on it may be the catalyst to the problem. I suggest since it was a used transmission to return it whomever it was purchased and procure a new (or new used) one. If this is a problem due to place of purchase and the seller refusing to take back (hard to do sometimes with private sellers) a now faulty transmission, you could check your local laws about purchase and return. Possibly you could legally force a return. For instance any used car can be returned by law in Canada within 90days of purchase if it breaks down for some reason, it is law that they take it back and return to the purchaser the funds of purchase. This law does not pertain to parts sold however, but a good lawyer should be able to make the case.

So, I literally just bought a 2004 Buick LeSabre and have just arrived home. It was about a 40mi drive and now the car is over heating and spraying radiator fluid everywhere!! Bought it from my father in...

Wow, thats going to be a sticky situation.
I would first let the father-in-law know what happened in case the car has some serious damage. You may need to sell it back to him.
It could be a sticky thermostat, failed water pump, or various other causes. Even a blown head gasket.

Just purchased 2000 Buick LeSabre. 56,000 miles, sporadic trouble starting--sometimes starts first try, other times will crank and won't start and have to slightly depress the accelerator and then will...

If it runs rough all the time, could be a bad coil pack/wires. If just starting and hesitates on acceleration, I would suspect the throttle position sensor.

My odometer is 110,000 that a subaru 2008 outback is that bad,i bought only last week

  • Not to bad. Outback is a good vehicle. With so many miles and it only being a 2008 I am inclined to think this was a highway traveled vehicle more than in town. This is good because highway miles is far better on a vehicle than in town miles. Some maintenance you need to either confirm has been done or inspected to see if it needs to be done. May also have some warranty with it to but warranties often do not cover preventative maintenance.
  1. Transmission flush - 20,000 miles
  2. Transmission Filter - 50,000 miles
  3. Radiator flush. - 30,000 miles
  4. Air filter. - As needed.
  5. Oil change. - 3 months or 3,000 miles - usually right away with new vehicle.
  6. Emissions clean. - 25,000 miles
  7. Brake inspection. Right away with new vehicle.
  8. Serpentine belt - 50,000 miles inspect often.
  9. Alignment check - Check is often free.
  10. Tires.

Idles erratically.Changed fuel filter

I own a 1994 Buick LeSabre. I purchased this car brand new. I now have over 150K on the car and other than replacing the tires, fuel filter, plugs and and alternator (with the exception of the tire, all other work was all done by myself), this car it has not given me any trouble. The bottom line, if you properly maintain a car, any car, it will be very reliable. In fact, I have owned several cars (9 to be exact) and they all have given me little trouble. Maintenance, maintenance, & maintenance!
