Toyota Repair/100k maintenance

Expert: Ted Ritter - 6/15/2009


Question
I just have a general question about what maintenance you would suggest at 100k miles for a 2000 toyota celica gt.  I also have had a p0420 error code aobut 7k miles ago, I had them just clear the code.  The cel light has occured about 1k miles ago then went off on its own.  Just curious to hear your thoughts. Thanks.

Answer
the p0420 is a catalityc converter malfunction code, it may be starting to go out and may need to be replaced. At that mileage the spark plugs should be replaced s well as the air filter, the coolant, the transmission fluid, the brakes checked, the tires rotated and the oil/ filter changed.
