Why is my oil light coming on when I slow down suddenly?


Check your engine oil level, when the oil level is low, braking suddenly causes the oil to surge away from the oil pump pickup in the sump and will cause the light to come on. Top up the engine oil as soon as possible or you will end up with a very expensive repair job

What causes the oil light to come on?


The oil light will come on orange if your oil level is low. The oil light will come on red if your oil pressure is low. The oil light will come on, then turn off if your oil level sensor needs replacing. Alex

My engine is makinng a clackin noise when i start it but when i press the gas it goes away but when i stop a light or something it makes the oise again


Sounds like the oil pickup screen is clogged causing low oil pressure at idle. Oil pumps do not go bad in these cars.

1990 buick lesabre when in drive seems like its in neautral


Hello, I'm not sure if you are still dealing with this problem, but here are a few tips.
1.When the car is running and at normal operating temperature, check the transmission fluid level. If the transmission fluid level is low, this will cause the Transmission to slip when in drive.
2.If you transmission fluid level is low, this usually indicates you have a leak. Transmission fluid does not need to be changed like other fluids such as oil.
3.You may also want to add a "stop slip" agent to you car, this may help or possibly correct the problem.
4.If all else fails, I would recommend you take you car into a certified Transmission shop. Please vote or rate this reply if you found this reply helpful.
