Question about 1988 Buick LeSabre

1 Answer

Throttle sensors going bad

I have put 4 throttle sensors on my 95 Buick LeSabre in the last 15,000 miles. The problem has accelerated with the last 2 sensors. Lasting only 200 miles before the check engine light comes on. I took the car to the Buick dealer this last time and had the car on the computer. It checked out as a EGR valve. I was told that to get a true diagnosis
of the problem, I would have to bring it back when the car is acting up.
The acting up is this. It will surge when you put a little pressure on the pedal. Eventually the transmission will not change gears. Then I have it checked and I put in throttle senors to make the problem go away until the next time. What do you think?

I had similar problem with my 1994 Buick LeSabe. after clening EGR valve and idle valve the problem almost disappeared. use trottle body cleaning liquid. be carefull with a gasket otherwise you will need to buy a new one. New EGR cost around $120throttle sensors going bad - 37e8c8b.jpg

WHAT WOULD MAKE MY CAR ENGINE WANT TO RACE FORWARD


A few possibilities:
  1. Defective throttle position sensor (TPS);
  2. Bad idle bypass circuit or idle circuit solenoid;
  3. Cracked intake manifold, throttle body assembly, or bad throttle body gasket (most likely);
  4. Serious vacuum leak somewhere.

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.

Can you tell me where the throttle position sensor is located on a 1990 Buick Lesabre?


look to see where the accelerator cable is and directly opposite thru the throttle body is the location. This is near where the air filter attatches to the motor

93 lesabre - starts right up but cuts off when you take your foot off the accelerator.


check your map sensor as well as the range on your tps/ throttle postion sensor and your throttle body gaskets sometimes that engine will get a air leak that corrupts the vacumn necessary to operate the fuel rail which in turn will shut the fuel off at a idle

My car was diagnoised with a bad air flow sensor


the mass air flow sensor is located under the top plastic engine cover. to remove this un screw the oil filler tube by hand and remove the top cover. its just to the right of center engine. unplug this sensor. next it has two screws to take this off. It is not standard screws so look at it. remove them and replace sensor. After install go to autozone and have the warning code removed. This is done free. 2000 buick lesabre

Check the ECM if it has the number 1228253 on it, this is what is wrong with it. Gm trashed all of these bad ecms. Get a 16198264 as they do not cause a cutting off problem . Get a delco ecm , aftermarket units will give trouble and may be a rebuilt 1228253 which is junk.

1992 buick LeSabre transmission troubleshooting!


92 Buick lesabre 97000 miles, on slow acceleration, @ 40mph going into 4th gear there is a mild chutter, same @ 50mph going into OD mild chutter and when down shifting from OD to 4th. All is when slow acceleration. When I say slow acceleration, I mean I drive like a older senior citizen when everyone behind me is annoyed I don't just donor and go. When I do romp to accelerate quicker, there is no chutter at all. Fluid is good and at perfect level. Any ideas? Great car just wondering the scoop is
