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.

 

mine did that when it jumped timing...........

 

fuel pump ecu! or fuel pump

 

Yeah I vote lean. Either because not enough fuel or vacuum leak of some kind.

 

i got the fuel pump check an its good, haven't check timing or vacuum yet. but will do. just broke my leg in a motorcycle accident, so can't do anything right now. thanks guys.

 

ignition coils could be going out. check engine light pop up?

 

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?.

 

check engine light is off.

 

AFM could but it would just shut the car off all together.

get ur ignition coils tested.
