i've been wondering about how to tune a fuel injection car? versus the old carb setup from my first gen, anyway my problem is i think its getting too much fuel or too little because it just drops from 1k rpm's to nothing

 

i think you might want to explain your problem a bit better.

Does the car run? Does it crank up then shuts off.. More info = better answers

 

it runs just bad idle / running too rich.
