1998 Toyota Avalon ProblemsMisfire 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.
The mass air flow sensor on higher mileage cars occasionally needs to be cleaned or replaced if sluggish acceleration is experienced or the Check Engine Light is illuminated with a mass air flow meter sensor fault code stored.
The EGR System tends to get restricted or blocked with carbon after 100,000- 125,000 miles which will cause an emissions test failure for NOX. If the EGR system is equipped with an EGR temperature sensor it will trigger a Check Engine Light for improper EGR flow. The repair is to clean out the EGR passages and the EGR Temperature sensor. Our technicians tell this repair is pretty straight forward and takes about 1-1.5 hours. It is also wise to verify the EGR system components i.e. the Transducer, EGR Valve and VSV Solenoid at this time.
