Sounds like the alternator is going bad and killing the battery.

Most likely your Generator has failed or you have a battery connection isssue.But based on the info you provided it sounds like the generator.You need to remove it or take the car somewhere & have the charging system tested.hope this helps

A few things could be causing this problem:

1. Vibration when running is an indication that one or more spark plugs are fouled or missing
2. Cracked/worn distributor cap
3. On all models except the Millenia, the fuel filter is attached to a bracket located in the left rear of the engine compartment, next to or beneath the brake master cylinder fluid reservoir

Not to scare or offend you but it could be many many things. It does help that the check engine light is on, though.
If you can go to a place like Autozone, where they check your check engine light for free, and post what the code was, I can give you a place to start.
I do not mind helping you further with a proper diagnosis procedure either, if you can share your vehicle information.

Sounds like a MAF(Mass air flow sensor, you can start by pulling it out, it's inside the intake box on this car. You can clean it with a high percentage isopropl alcohal or MAF cleaner, this sounds to be the problem, if it is really bad, you can unplug it temporarily, it will not have as much power but it will run better. If cleaning it doesn't fix it, then you will need to replace it, ensure not to touch the sensor itself at all.
