Service engine soon light

What are the codes you have?

That service engine soon light is the same thing as a check engine light. You need to get the codes read so you can fix the problem. when a critical sensor quits working the engine will either stay or revert back to closed loop mode which is the mode it uses when cold. So it uses a lot more fuel just like it does when cold. The codes stored by the computer should say which sensor has malfunctioned.

You need a new wheel bearing, This also happened to my olds alero, make sure 2 jack up each tire 1 at a time and pull back and forth on them checking for play, once you have found the 1 that has play or wobbles that is the 1 that needs a new wheel bearing

Yes, it means it needs its routine periodic service. Not performing maintenance will inevitably lead to more expense.

There is definately something wrong w/ the car. The best thing for you to do is go to Autozone & get a "free" Check-Engine test. The people there are always happy to assist. They will give you a error code & provide a description on the issue. Once you have that, log back in & I can possible guide you from there.

ok you service engine light is you computer telling you that something is not right.
try unhooking your negative on your battery ( that resets the codes) if this persists then invest in a code reader, let me know what codes come up

you should check if the Fuel is flowing properly

If signal lights are working, probably a failing headlight switch. Even though fuses seem OK, you can try replacing the appropriate fuse.

i have never seen it on the console do that ,i know my engine light has stayed on for about four years and it is the turbin speed sensor in transmission but it dosent give me problems but then it started to flash and it was running bad ended up being injectors

The MIL light AKA service engine soon light comes on to warn of a malfunction in the emission control system or a problem with electronic engine controls like fuel control, there will be one or more trouble codes stored in the PCM (powertrain control module) to show what system or sensor has an issue/problem, take the car to any Kragen Auto, Auto Zone or other chain parts store and they will test it for free, write down the trouble code or code's and post them back on this same thread for me to look at, then we will have some info on what to fix to get the light to go out, also have them reset the light when they test it, it will come back on in a few days, but maybe we can fix it before then, OK?
