start, idle, fuel? Problem! need help!

my swift is running like a sh*t...

when I start the engine at the mornings it can't unless I hit the throtle.. When it starts and I try to go it stalls constantly...

If the car is not warm, when I stop in an intersection it stops...idle is ~400rpm when it's cold.

In warm the car runs better but I notice that I hit the throttle pedal and it doesn't do nothing til 2-3mm (neck hitted).
The exhaust smells fuel and can't reach 450km/tank...

where is the problem? maf, tps, idle valve??
Thanks mates!

My car was being a little weird recently, idling at funny speeds and revving itself to stay running, turned out to be a cooling problem

self diagn. tell me MAF, I've changed and run for about 100km now diagnossis tell me Normal...

I don't know if mpg had corrected yet, lets see in a pair of days.

but I feel the throtle pedal like a sh*t, must check tps...
let's see, thanks!
