87 turbo not starting
 

after driving my 87 turbo supra i let it cool down for a good 40 seconds or so but sometimes if i have to start it back up to soon the car starts and goes to like 400 rpms and immediately stalls, i have to start it and keep my foot on the gas until it revs up. any ideas what could be wrong with it?

possible bad air intake sensor? hole in the ducts? what have you checked so far?

Better Description
 

It would be well worth it for you to give as DETAILED description as possible. If it makes a humming noise, then don't say a noise, tell us it its a clunk, humm, bump....w\e. Anyways, I can't realy narrow down what that problem could be.

I would suggest that you could have a problem in your electical, maybe like the previous person said, your actual computer components may be miss reading, or possibly they are on their way out, or are already dead.
