I have a Toyota Camry (00' or 01'?) with 253000 miles on it ;-). It has a problem with overheating, and coolant needs to be added directly to the radiator when the car is cool. My dad said the thermostat and radiator have been replaced a month or two ago. He said something about a poor head gasket on it too? The fans must work, because when I turn the heat on the engine temp drops to normal operating temperature.
Also, the car runs rough on idle, esp. in drive. The plugs & wires have been changed within the month as well. During acceleration the check engine light blinks, and then goes back to normal when it catches a gear.
It's not worth taking it in at this point with that many miles on it. It just has to make it to the summer time, and any added time after that is a bonus. What could be some of the problems/quick fixes I could do to it?
