I have a Mazda etude 1.60ise 2001 model and I am experiencing intermittent power loss when I am driving. The duration of the loss has now extended from a few seconds to a couple of minutes. When the problem occurs I floor the accelerator and the car is sluggish, I also get petrol smell, and when I put the car in neutral it idles very low. I have serviced the car after the first couple of times it was doing it, but now the problem seems even worse.
