would the security light saying on while my car is running(not running well)have something to do with my car not running properly? i have changed bad coil,ok for about 1 day,changed board under coils,ran good for about 5 miles then started stalling again and popping out of intake,only way to keep running is to either step on brake and gas at same time or put car in neutral and feather the peddle.so many diff sites tell you so many diff. things makes your head spin.can just to keep changing out parts until you find the wright one makes no sense.HELP

replaced one of the coils that was ng. now car has a back fire through intake,the plug wires are not crossed.after driving for awhile about 5 min.city driving.it stalls and the only way to keep it running is to step on brake and gas at same time or put it in neutral when coming to a stop.

Bought my car with sugar in my tank. Replaced fuel filter and fuel pump. I need to get the remaining sugar out. What else need replacing?

as you drive it seems to die, like not enough gas......

got engine to turn over but will not fire...checked fuel pump its good...sprayed starter fluid while turning key its no good...have read some suggestions for crankshaft sensor...but would like a better idea of where it is

All the lights work except the headlights

Replaced actuator still won't blow cold air out of driver's side vents was told it is the gasket that sits in actuator box

Horn doesn't work after sitting for a year. Checked fuses, and wires to horn

all lights come on but starter is dead. after a few minutes or even a half hour .. turn key and car starts fine..

Also, any pictures of location of canister and routing of VAC lines???

My mom had a 1988 Buick LeSabre and she has to usually (but not always) press the brake pedal to the floor to get her brakes to work. She managed to get the car to the shop and after evaluation, the shop determined that her brakes were fine, no leaking brake fluid and stated..."Needs new R/F wheel speed ABS sensor. Sensor wire is cut or damaged."...After many attempts, on their part and my and my husband's parts, it has clearly been determined that this "R/F wheel speed ABS sensor" has been discontinued for the 1988 Buick LeSabre and CANNOT be found ANYWHERE! Does this sound right to you? Would this sensor cause problems with the brakes? Would it cause brake failure?What should we do since the sensors have been discontinued? Is there a "universal" sensor that can be used on her car? My mom is 82 years old and we want her to be completely safe and worry free! Any input that you can provide is greatly appreciated! Thank you!

Had the system completely flushed this winter, but the output hose from the heater is still cold even with the engine at operating temperature. What should I look at next?

Tried taking batteries out of both fobs and pressing panic and unlock. Could only stop horns by unplugging them. All other features work. ?

also changed timing chain aligned correct marks. checked balancer for bad fins. I'm running out of places to look. connectors have no bent pins. all above have been re and rechecked.

The Buick has 130,000 miles and in Jan. 2014 I replaced the No. 4 cracked plug. This week, Aug. 2015 I had to replace it again. Cracked again. Why?????

I have a 94' Buick Lesabre Custom that just started making a fluttering/clicking sound while I'm driving. The sound is much louder when I brake and it sounds like it's coming from the rear end of the car but I could be wrong. I was told it could be a U Joint but then I found out that model doesn't have a U Joint. Can anyone give me a better answer than brakes and rotors? Or more reasoning behind what might be wrong?

changed cam and crank sensor and igniter under coil pack. still no spark
