rx8 engine hesitation at stop
 

Usually happens when car is not fully warmed up or cools down after a while not in use(recently twice only). The car is usually 1/4 of the way warmed up and ill come up to a stop. I step on the accelerator no more than half way and it wants to go but suddenly quits for a second, then continues on. Doesn't happen always, but every once in a while. yesterday it scared me because I stepped on it and seemed like it wanted to die out because the red battery warning light flashed before the engine reved back up. I also go easy on the car until its fully warmed up shift @ 3k AT. I am running catless, bhr ignition upgrade, newer full fuel pump assembly from a 20K mile shinka, spark plugs with 1.5 years on them, oil is at level and should be at 2000 miles since the last change...Im thinking maybe its time to clean the filter on the aem intake...or the maf

thanks for the troubleshooting help.
