I have a 2000 Toyota Corolla LE that ran very well until about a month ago. It has about 146,000 miles on it. A month ago it started hesitating from a standstill and the engine ran extremely roughly when trying to move the car. But when I put it in low gear it did much better, although not great! When in Drive it barely moved the car at all and would frequently stop running completely.
When I took it to an auto parts store they hooked it up to their computer and it read out that I needed either spark pugs, spark plug wires, or a new coil. I have replaced the plugs, but that made little difference. I then took it to another auto repair place that told me that it was either a problems with valves, or a ‘problems in the lower engine’. I don’t know what that latter problems means but either way it sounds like it will be very expensive to fix.
Since the car is 14 years old with almost 150,000 miles on it I question if it is worth the 1200-1500 dollar estimate they gave me. The other thing that makes me pause is that it runs just fine some times.
Does anyone have some advice or ideas of what it could be, and what do you think of spending that much on it?
