I have a 95 buick le saber 3.8 ltr. It back fires when running. But when check engine light is on it wont back fire. It does sound louder with check engine light on. Changed coils. I need help trying to...


You need to scan the computer for trouble codes. If the light was on, there must be codes set. On a '95 Buick, it would be OBD-1, On Board Diagnostics-first generation ('96 and later is all OBD-2).
The diagnostic connectors are different for OBD1 and OBD2, but in '94 and '95, GM was on some models using a "hybrid" diagnostic link connector. You will just have to find the right diagnostic connector to get your codes. The guys at autozone or a national parts store who do engine scans for free may help you figure it out. If it is a straight forward OBD 1 connector, a cheap code reader could scan for trouble codes. For the OBD1, you can also use a jumper wire between terminals
A & B of the diagnostic link connector. Turn key to on, and two digit codes will begin to flash on the check engine light. Code 12, for instance, would be a flash, pause, two short flashes, and longer pause before the next code appears. Code 12 by the way, just means that the computer is in diagnostic mode-after that any set codes will appear or be flashed. Code 55 may also be flashed-this code means the end of codes that are set.

Getting codes from a 2000 buick lesabre


Buy yourself a OBD-II code reader, V-Checker (online) or one from Harbor Freight Tools. $50-ish range. This will let you read the stored codes and even reset the check engine light, useful when the problem has been solved. In general the Check Engine Light doesn't reset itself. The computer knows something is operating out of specifications, sets a fault code within the computer's memory and illuminates the Check Engine Light to let you know something "flipped" when it should have "flopped". (That last part if just an electronics technician's joke derived from a chip called a flip-flop, used here with jocularity to indicate a malfunction.)

On the dashboard of my 2000 Buick BeSabre, it say: It needs service. What does that mean?


Service generally refers to a need for maintenance, It could be almost anything. To find out for yourself, get a OBD-II code reader and plug it into the diagnostic port usually found under the dash close to the steering column. Advance, Auto Zone, even Harbor Freight Tools sells them for about $50 and they let you reset the check engine light. Worth their weight in gold if you ask me, you will use it more than once, trust me.

1986 buick lesabre 3.0 L engine coolant sensor .


Its just a relay or the computer or sensor, check a manual at an auto parts store, they can look it up. but to fix it quick, just run a new power and ground direct to the fan, so it runs when you turn the engine on, I drove My 90'Olds cutlass like that for years.
