If there is carbon build up in the combustion chamber it retains heat and can cause pre ignition detonation preventing the full advance of the ignition timing by the engine management control.... There is another person on this forum that had the same problem with his automatic Fit, and by adding some fuel injector cleaner and driving at higher RPM than he normally did, is now saying that his car has never run better.... He had spent a great deal of money for a super charger prior to this and his car even ran poorly, until doing this... I believe that the hot weather is is a contributing factor in your loss of power, but low RPM driving. the higher gearing and torque converter weight of the automatic will cause carbon accumulation.... Get out on the road put the throttle down and blow it out..... You can't blow it up or hurt it by doing it and that is what car owners have been doing since they have been making cars.
