Car choking when the gas is stepped on or rev too quickly

**hungzki** · 04-03-2009 08:19 PM

I am having troubles when I step down on the gas petal then the car sounds like it is choking very badly resulting in complete power loss and sometimes it would let out a loud bang which sounds like it comes from the exhaust.

This happens more generally when the car is warmed up and when I step down on the GAS petal quickly. It does not happen when i rev the car up slowly. It only happens when I try and rev it up quick. This can also happens when i leave the car neutral so i don't think it has anything to do with the clutch.

Can anyone help me out her or give me a slight idea what could be wrong with it?

Possibly a collapsed cat? Have a mechanic check out your car.

Does it only happens when the weather is hot? Seeing that you are in Victoria, we've been experiencing rather hot days until of late.

Such a common sounding problem,it's like it's flooding it then bang! explosion...I've always wondered what causes this.

Your fuel pumps gone. Let me guess, if you accelerate slowly the revs build up but there's almost no power or movement? Then when you decide to floor it, it splutters, chokes and goes BANG kinda like "vrOmmORORMMM BANG BANG vroROORMMA AAAAA BANG BANG"? It idles fine as well? Takes a little longer to crank than usual (more than two starter motor turns/cycles), maybe for or 5 turns before firing up?

If your answer is yes to any of the above, your fuel pump is officially rooted. Have a done in cat or bad exhaust will make your exhaust smell like dead bodies, it'll go BANG...but it normally won't make your car splutter and lose that much power.

Well, the car sounds like vRooooOm PHUT PHUT PHUT BANG VROOOM. Yes it does take more then 2 cranks to start it up. Thanks for this, I had an idea that it was something with the fuel pump. Will go check the pump and exhaust and let you guys know.
