I know what all of your are thinking when you see 300,000 miles. BUY A NEW ENGINE! well the fact is I can't and the my 1989 turbo supra 5spd still runs hard and strong.
I've had this car for 2 years in september.
I've fixed things here and there like when the battery kept draining over night all we did was change the wireing we service all the fluids every 3 months. we changed hoses and other small componets.
just recently the car has died on us.
We are certain to believe that the Air flow sensor is dead, because we cleaned it with the wrong stuff.
Here are the symptoms:
ruff idle
black smoke
check engine light

Thats all I can think offthe car hasn't been running for about 2 weeks, also the starter is broken the is the main reason it hasn't been started.
To get more to the point when we messed up the air flow meter the car sounded horrible the idle would drop and the car would shut off if you touched the throttle by pedal or from the engine.
We had to have a rolling start we decided to take it for a right in the condition it was in
It ran fantastic the engine light went off at high rpms but when you came to a stop the engine light comes on and the idle is ruff, you would have to rev it up to keep it going.
Thats what puzzled us the most.
So what I am asking is if I were to get a new air flow sensor would the supra be back to normal?

P.S. sorry for the long post
also i am only 16 years old
