No warning and approximately 80,000 miles -the timing needs replaced. Mechanics state this is common with this model and they recommend a new engine replace the original engine. This car has under 100,000 miles on it. The cost of the repair is out of my means. The car is paid off, however, I cannot afford the repair. Is there anything that can be done?
