Engine light won't go off - printout says it's running lean - replaced mass airflow sensor, upper & lower O2 sensors, spark plugs, wires and coils. What else I need to do to get the light to go out so it'll pass inspection?
View 4 RepliesI have a 1998 Buick lesaber it ran hot the other day [temp light came on] do I pulled in to gastation and the overflow tank was empty I filled it to the hot line and ran it for a few minutes light went off drove 8 blocks to my house let it cool down and opens the radiator cap no coolant. I checked the overflow tank empty too. So I got some coolant from my garage and poured it into the radiator as I was pouring it started to leak out somewhere on the upper passenger side of the engine under the plastic noise cover and behind the pulleys. This happened while the car was not running. It's my family's only car so I can't tear it apart until the weekend but where to start or what parts to have on hand.

View 1 RepliesMy '98 Buick's AC works well when I take it to a mechanic. But when I leave after they say, 'it seems fine now,' a few miles later the cold air starts blowing through the defroster vents, still nice and cold. Then it comes back down to the dash and then goes back up to the defrost. But sometimes it stops blowing altogether, it doesn't blow anywhere! Nothing, not even warm air. And then later everything is fine again, until it happens all over again and I take it to another shop when I hear 'it seems fine now.'.
View 2 RepliesMy wife's 98 LeSabre will occasionally cut out or stall. It usually happens at low speeds and she thinks it may be more frequently on a right hand turn. The engine can always be restarted immediately. There is no other symptom, no check engine light on when running. The car runs well and has ~125000 miles. Sounds like an intermittent connection or short but where?
View 2 RepliesI am currently driving a 98 Buick with the 3.8 V6 and 120,000 on the clock. The car runs 100%, and its paid for
My problem is I seem to be losing coolant, at the rate of about the entire overflow in 2 weeks (I only drive on avg 15-20 miles a day). The problem is I have no leaks. I even went so far as to pull the spark plugs and they all looked good (none of them looked "steam cleaned"). I put florescent dye into the rad, and I can’t find a drop of coolant anywhere. The intake gaskets have already been done on this car, and I triple checked around it with the die.
Rad, and hoses all check out, no dye in the oil, no dye at the heater core/AC drain under the car, the core plugs are fine, around the head gaskets seem fine as well.. I CANT FIGURE THIS OUT !! I am 100% losing coolant, but I can’t find hide nor hair of it..
I know I can keep adding coolant, but I like my cars as leak free as possible and if it is something bad, I want to know about it now not later.
My dad has a 98 Buick La Sabre that will shut off at times. It once shut off as he was turning on the air cond. last summer. Right after it stalled and would not start he attempted to open the windows but they would not work. After a few hours and cooling off it started and the windows worked again. He took it to a shop who said it was the map sensor. They changed it but the problem happened again a few weeks after. The fuel pump has recently been changed along with the fuel filter.
One mechanic suggested it could be the ignition control modular or knock sensor. He recently got a different car so I an going to test drive it for a while. If it shuts down I will test for spark to confirm it is not a fuel problem. I will also try swooping relays to see if that is not the problem. I will be cleaning all the connections I can find with contact cleaner as it can't hurt.
What could be the problem. Could it be a short, a bad wire that once it gets to much of a load on it cuts the engine off?
I am having problems with with the rear defroster and the a/c in my '98 Buick Lesabre, they went out at the same time, and I checked the fuses in the fuse box, and the meter says they are all good, the fan motor isn't running either, and I think that they are all tied together.
View 14 Replies'95 LeSabre, 250K, runs great. Check engine light on randomly and signs point to a computer malfunction causing the light to come on. Is it true that only a dealership can replace the computer, not an indy mechanic? How much for the repair? Will it run ok w/o a new computer?
View 6 RepliesI have a '98 Buick LeSabre, 112,000 miles and it's white. When I put the ignition key in and turn it without starting it completely I get a humming noise coming from the rear of the car. It lasts about 5 seconds and stops. When I start the car it begins again and continues all the time I'm driving. A friend suggested it might be the fuel pump.
View 1 RepliesMy vehicle is a 98 F150 5.4 ltr Triton. I got a check engine light on and the error is "bank 2, system too lean." I read that this can be caused by a few different things like vacuum leaks or fuel filter and so far I haven't been able to narrow down. It started with occasional shaking at idle and its happening more as time goes. When at idle it often makes a sound like slurping the bottom of a drink with a straw and shakes intermittently. The fuel economy seems to have gone down. Sometimes it seems like it almost dies in idle, but always keeps running. It runs great when I push on the gas.

View 3 RepliesI have a 94 buick lesabre custom that is stalling intermittently and runs rough intermittently. We have had it for diagnostics and it could not read the codes. We changed the computer and it still can't read the codes. The diagnostic tool says it cannot connect when it is plugged in or it displays white flecks like snow flakes on the tool screen. It is an OBDII. The pin structure of the data connector port is two pins top row and bottom row two pins some blanks and one pin. We don't know how to fix it with no diagnostic codes and we don't know what to do to get the codes because we have changed the computer.
View 8 RepliesI have an old 98 Lesabre, and it runs and drives great. When I first got it I had to do the Vacuum line mod on the programmer to get the HVAC to blow out the face vents. That was the best $1.60 and 30 min I spent on a car
That mod still works and was done about 1.5 years ago, the ENTIRE time i have owned the car the temp blinks when I start the car, but the HVAC has always worked fine so I paid no attention to it. That is until 3 weeks ago when I had to replace my intake manifold. I disconnected the battery without turning the system to "off". I have been doing a bunch of reading online, and it seems I may have thrown the system's sync off by doing this.
Right now my problem is this, colder air coming from the pass side then the driver’s side. When I start the car it will seem synched for a few seconds, then it will start blinking and both vents will go FULL COLD, eventually it brings the temp back up the d-side gets hotter than the p-side. I have done the following:
- gone through AT LEAST 50 on/off cycles
- Removed the 9c fuse to try to reset
- Pulled down the glove box door and watched both the upper and lower blend doors go through there whole range of movement (which they do)
- Tried to re-sync by pushing the temp full hot, then full cold a few times in a row.
Besides getting this scanned by a tech 2, which is my last resort, is there anything else I can do?
I have a 2000 buick lesabre v6 3800 series 2 engine and every now and then when accelerating it will miss out, I don't know what it could be?
View 6 RepliesI purchased a nice 03 Buick lesabre with only 40,000 miles mint , well after driving and enjoying it now for 2 months, I now have a red flashing light left top side of my radio. However it still works and it does go off when I start the engine, what does this mean because I pulled out the manual and this is what I have, is it a normal thing that was just delayed in happening for some unknown reason?

I have a 93 Buick Lesabre and the ABS light was coming on and off for about three weeks.Now it stays on all the time. Just recently I had the brakes completely lock up on me. In my car you have to apply pressure to the brakes to even get the car to shift into gear. The car will drive for about a mile and then all of a sudden the brake pedal is completely hard and the car will not roll forward. It does it completely fine in reverse. My calipers are good and there is no sound of them locking up. The pads are in good condition.Then after this happened to me twice in a two mile drive, struggling to get it home... now a light in the dash flashes SECURITY. It is strange and I know my brakes are in good condition and there is no abnormal wear and tear.
View 4 RepliesMy buick has a weird problem, basically it wont start the security light comes on, nothing and i mean absolutely nothing works inside of the car and the power window circuit breaker under the back seat is burning hot, obviously its an electrical problem but I am thinking its the body control module but I want to be sure .... what it could be?
View 5 Replieswe just replaced the intake manifold and also put on new spark plug wires and plugs. now the engine is missing but only after it warms up. i double checked all the wires and connections and they looked good. is there something obvious that i should look at since it is still doing it?
