Trouble keeping car runnin

Question

car starts up and it revs real high then settles down for like a sec then dies. its 85 trans am fuel injected

Answer 1

Sounds like a normal running Pontiac to me.  Check for a vacuum leaks at throttle body and manifold.

Answer 2

I have an 89 chevy and this happened to me several times before I got it fixed.  Eventually, it won't start at all.  Have your oxygen sensor on your fuel injection checked by a mechanic.  

Answer 3

some one droped a ford engine in you pontiac lastnight, to see if you could tell the difference
