Xg300-While driving, the car went from running fine to no acceleration at all. The engine was still running, however. I had the car towed home 2 days later. When I went out to see if it would start, it did. Then I put the car in reverse to back it up and it stalled.

It was running very rough last June. I had the mass airflow sensor cleaned out and a new air filter put in. It ran fairly well after that except it still got really bad gas mileage. The trans mission leaks a little and it slips slightly.

The slippage is the main cause of the poor mileage.
