Have Toyota Questions? Ask a Mechanic for Answers ASAP
Hello. Welcome to Just Answer. Please allow me to assist you. Could you please let me know if the amber Check Engine light is illuminated at the instrument panel. Thanks
It would be prudent to get the car scanned, by a really good scanner (one that can read "history" codes). Since the light flashed, this indicates you have an intermittent problem which may have set a history code. If we have the code, we can pursue the cause and then arrive at a cure. Speculating on issues like this can expend a lot of money needlessly. We need to know the cause before we start purchasing anything. I can tell you this, though: These cars run very poorly on any spark plug other than Nippondenso spark plugs. Also, if the ignition coil(s) is/are not factory, this too can cause the problem you are having. If you do not have Nippondenso plugs in this engine, I highly recommend you get a set form a Toyota dealer and have them installed.
