The engine light was on in my 2006 liberty crd then went off but it's still doing the same thing. When I'm driving and i press the gas pedal there is a noise of air. Imagine when you are filling your tire with air and sometimes they aren't properly connected and air excapes. That is the closest sound i can think of. I was thinking that maybe the fuel line some where has a leak and for the proper ratio of gas to air it's sucking in more air since I'm assuming the leak is just before the cylinders. Because it's using more fuel then it should. Or maybe for some reason it's sucking in lots of air and it's compensating and using more fuel to keep the same fuel to air ratio. But today when i turned it on and after driving out of the parking lot and onto the street. When i press on the gas there was no power. As if the stock turbo for the engine wasn't working. Anyone knows what might be wrong?
