Get a Diagnostic from Fiat...

Costs £30 ish and they'll tell yu exactly what's died...if anything!!!

Could easily be MAP, Lambda or Crank sensor related!

will that work on my car it is a 900 sx im not too sure there is any diagnostic features on it

Yes, there are plenty of 'diagnostic features' as you call them. The fuel injection system relies on the correct information being received from numerous sensors. If a sensor sends the wrong info, then the wrong sum is done by the ECU and the wrong result sent to the injection. Another sensor then picks up that something is wrong and resets the ecu, then the original sensor changes it again, and so.

However,

Have a look for a loose or damaged vacuum pipe, or split pipe end around the throttle body and map sensor. Additional air can lead to the sort of problem you are experiencing.
