Misfire and/or Check Engine Light Due to Failed Ignition Coil on Lexus ES300

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 blinking, loss of acceleration, smoke coming out from under hood; melted radiator reservoir; two rear coils replaced. Three days later, check engine light on solid, loss of acceleration. One more coil replaced. Two months later, misfire on #2. Replacing remaining three coils!
The check engine light was on. I took it to Jerry Deluca's Auto Repair on Williams St., Staten Island. They told me the two front fuel ratio sensors needed to be replace for $610 including labor. He also recommended I change the spark plugs and ignition wires for another $300. He said it took 1 1/2 hrs diagnosing my problem and charged me $155 for diagnosis labor. A total of $1,065. Just to verify, I took it to the Shell Station Garage on Forest Avenue, Staten Island. They diagnosed it no charge and told me three ignition coils needed to be replaced. He said he would replace them and tune-up the car for $550. I went with the Shell Station Garage on Forest Avenue. I had to pay Jerry Deluca for the diagnosis labor to retrieve my car though.

Same problems and symptoms, took to mechanic, computer did not register the failed coil though. Mechanic swapped coils twice and identified the defective coil. Replaced two coils. One year later more coils failed, will be repairing again...

Check engine Light started blinking when engine was misfiring. The issue was probably due to an small manifold oil gasket oil leak. Four months later the Catalytic converter is clogged and needs to be replaced.
