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

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 came on and dealership could not determine issue - went to firestone and they fixed it

Extreme sluggishness when accelerating. The engine light flashed a few times and the went solid. Each time I would accelerate from a stop the engine light would flash and once I reached a desired speed it would stay solid. I brought my car in the next day and it was determined that #3 and #6 cylinders were misfiring due to a bad coil. Problem resolved by installing a new coil assembly for those cylinders.

Some hesitation when accelerated and then the check engine light flashed. I pulled over, shut the car off and restarted. The warning light went off, but the hesitation continued. The next day, the warning light came on and stayed on solid. I brought the car in and it was determined it was firing on 4 of 6 cylinders and needed ignition coil. It was fixed within a few hours and is driving perfect again.

Severe hesitation with backfire noticed when accelerating and would even out with the power called for whether up-shifting or cruising at speed and needing the extra boost. Brought this car to the repair shop where it was put on a computer and run under various conditions where a bad coil was finally diagnosed. Coil was replaced and engine runs as expected.
