House, can some tell me what's wrong with my car with the engine oil indicator coming on? the engine does not run stable and can even go off after applying brake. no smooth ride at all!

when was the last time oil got topped up in your car and also when was it changed ?

as for the engine start with basic changing the plugs and put that addictive that cleans your injectors

Oil Light:

1) Could be due to oil starvation - check your oil level.
2) Could be due to low idle - can your vehicle maintain an idle constitently?

Engine:

1) When was the last tune up? Air filter, spark plugs?
2) Are you throwing codes? If so scan for the codes.

Though doubtful but not improbable, check the connection at your oil pressure switch or even the switch itself.

thanks all.I topped the engine oil and the light is off. suprised because serviced the car about three or 4 months ago and did not make any long trip. However, planning another servicing this weekend in that case.

Somorin,

The car can only maintain idle state for few minutes. the moment the engine warms up it will start fluctuating. the RPM niddle goes between 0 and 1. this is another issue with the car.

Also, the radiator fan suddenly started rotating permanently.

Is VALVOLINE a good engine oil?

For your engine fluctuating you have a vacuum leak, one of the hoses that goes from the air box to engine has been removed ,not installed properly or cracked.There is another hose from brake booster Behind brake fluid reservoir that goes to the engine can cause that too.

Look at the Quest in the attached link

Thick black hoses and smaller one are what you are looking for some are for coolant that is why I said hoses from the airbox.

Vavoline is better that those visco 2000, ambro Major player in lubricants look for 10w30. your engine must be leaking oil.change oil every 3 months

Is your fan rewired? your thermostat removed?

Thanks a bunch Sultaan. great explanation. i will look at all these and revert ASAP.

One more thing; Please what could be wrong, front A/C vents not discharging but the back vents excellent?

To the enire house, kudos for your help.
