Vitara! Gasping

Help!

I havent got the knack of including smilies (so if anyone can help please do)

The problem is a fuel injection Vitara Gasping! I say this because it will sart & run for a while. If I try to tread on the gas it dies. Done all the normal checks so is there a trick waiting to learn.

if your engine uses an Air Flow Sensor, that sounds like it, or MAP sensor. I'd have a diagnostic done on it.
