1998 Toyota Avalon Problems

Misfire and/or Check Engine Light Due to Failed Ignition Coil

On higher mileage vehicles, an engine misfire may develop and/or the Check Engine Light may illuminate due to a failed ignition coil. It is not uncommon to replace all the coils when the first one fails in order to prevent return trips to the repair shop.

Check Engine Light Due to Failed Oxygen Sensor

The Check Engine Light may illuminate because a component of the oxygen sensor stops working. As a result the engine computer is unable to determine the proper ratio of air to fuel for the engine. Replacing the failed oxygen sensor should correct this concern.

 

Oil Leak From the Valve Cover Gaskets

The 6 cylinder engines have a tendency to leak oil from the valve cover gaskets, especially the one near the firewall.

1998 Toyota Avalon Reviews

Rated
based on 2 customer reviews
My car is making a knocking noise increasing in loudness. If it is not the motor, what else could it be? My car has slightly over 230,000 miles.
This car now has 104k miles and it runs beautifully. All I had to do is replace the rotors, brakes, tires, which are all due to the high mileage. The mechanic tells me it will run for some time.
