92 sc400 runs rough no power can't accelerate
hi i have a 1992 sc400. i was driving one day and the car started acting up. it felt like i lost all power wouldn't go pass 5mph. as i floor the gas pedal the engine would cough then engine would die out.. i had to tow it home. after getting it home i took the throttle body off and clean it. change spark plugs and wires. it start right up. but idol rough and sounds like lacking air. if i accelerate it the engine would die out. if i let it run, it wound run for like 5 minutes then die out. please help thanks.

oh is there any way of bypassing the mass air flow meter (MAF) and the throttle position sensor (TPS). cause i know those are usually the cause of lacking air right?.
