    Solution: change spark plugs to Denso SC16HR11

    My dealer changed my spark plugs 5 month ago to NGK ILKAR7B11 on sheduled maintaince. This cause the acceleration problem to the car.

    It took me 3 month to admit there is something wrong in my car. Took me 2 month to find solution. From now on I will fix everything myself.

    Also Bosch air filter was 5% of the solution. 10% of the solution was from vacuum the hybrid battery fan. 85% of the solution was from spark plugs. The old air filter was also 5 month ago from my dealer. It was PURRO PUR-PA8098 air filter that cause 5% of the problem.

    How did you determine the percentages?

    It would be interesting to see what was showing as the Misfire Margin with the ILKAR7B11, and then after you changed to the SC16HR11.

    I determined the precentage from my gut feeling.

    I didn't show any dashboard light or OBD code.

    I know people who votes like that at the polls and don’t worry about the candidates’ values and policies.
