Got a question for any auto mechanics on the forum. Had the vehicle inspected. Problem is, it's my Mom 's car and she is unable to drive it at the present time. She was supposed to drive it 100 miles as per the mechanic, he said he cleared the computer and needs to check it again after 100 miles. If that car gets taken back to the mechanic before 100 miles is put on the car, will anything show up on the computer to cause it to fail the computer test ?
