How do I get change engine oi light off in my 1999 Grand Am?

Before i can render any assistance you must first find the source of the oil leak, this requires that you have the engine cleaned of all leaked oi and dirt that has attached to it, then drive it look under the car and try and see the source.

The service engine soon light is an indicator /reminder for you to do some type of maintanence work on your vehicle, depending upon your mileage that you have accumulated on your car dictates the sort of maintanence needed on the car.
Can either be as simple as an oil change or as complicated as a major service/tuneup, oil change, transmission change, wheel alignment, brake inspect, tire rotation etc.
Once the work is performed the technician must turn off the light.
Reference the dealership or reliable repair shop for further information.

INSTALL OIL COOLER
-clean the oil cooler contact surface on the oil cooled mounting
-install a new O-ring to the oil cooler.
-temporarily install the oil cooler with the nut
-apply a light coat of engine oi on the threads and under the head of the relief vale
-install the plate washer and union bolt. torque 78Nm (800kgfcm, 58 ft lbs.)
-tighten the nut,torque 8.8Nm (90kgfcm, 78 inch lbs.)
-connect the 2 water bypass hoses to the oil cooler.

HOPE THIS CAN HELP.

You need to have the vechicle scanned for codes.I believe you are going to limp in mode on the computer.Have them check all codes,transmmission and body along with engine.

To reset the Change Oil light, open the driver’s side instrument fuse panel cover and turn ignition on engine OFF. Press the RESET button and release. The change oil indicator light will flash. Press the button again and the system will be reset.

Good luck and happy new years.

disconect the negative battery lead for a few seconds and reconect

Sounds like an air leak somewhere after the air filter chamber.With engine idling spray some carb cleaner at different areas along the intake hose and the intake manifold,any place air can get in.If rpms change you have found leak.

Hello jsnmurry: The reset for the change oil light should be as follows. Turn the key on engine off. Press the accelerator down 3 times quickly. Be sure to press all the way to the floor. Turn the key to the off position. Start the engine the light should go off. If you should need further help please just ask. Thank you for using FixYa. Roger

I had the same problem I believe.....
Changed the spark plugs and at the same time I changed the oil & Filters, (Oil & air ). You may not need to change the air fliter, But mine needed it. With the step buttons on the overhead, I could not find any reset. (my check engine light staied on) I'm no Darn Computer geek & frustrated easly by them. LOL ....So I disconected the battery cable, ( waited 15 to 20 sec) then reconnected the cable and this resets the computer. No more worning signs.
You may just need to change the oil & filter and reset the cp. Hope this helps
