While driving a 1997 Toyota Mark II in Japan the car starting slowing down while accelerating. At complete stop and in drive it seemed I was in neutral. Few minutes passed and was able to drive again. Slight hesitation and acts like a hiccup. Could this be a mass air flow sensor problem. Also the transmission fluid is normal. Car has 200k on it not sure if trans filter ever been changed. One more after driving for 10-15 minutes the problem disappears. Check engine did flash once and weird that the overdrive light started to blink. Thanks in advance. HM2 USN Okinawa Japan.
