My car has 160000 miles.
My car has an automatic transmission.

If the check engine light is on then you will have a stored code in one of the computers in the car. It will store a code anytime the light is on. You may have a problem with the fuel pressure or the mass air flow sensor. If your scanner does not get codes then have another mechanic scan the computer with a different scanner to see if there is stored codes.
