First let me explain the situation..
I've owned a mazda3 05 since 06.
Was a semi graduation gift...
long story... Blew the tranny due to negligence.( 1st car.. didnt know anything)
Now as the years have gone by.. my mother and sister have been driving the car.
They havent done any maintenance on it at all... I lose my car, and start driving the mazda again.

Now The check engine Light is on.
I started the car up yesterday to go to the store,
The car started to idle funny.. then it dropped below 500rpm and turned off.
But before that.. I gave rought idol, as well as this jerk.

Is it the motor mounts and fluid change would get me back up and running, that way I can get the rest of the issues fixed.



Motor Mounts?
Tune Up?
Any suggestions
car has over 130k miles.
