Here is a weird one for all of you, when on hard acceleration my car will make a garggling sound at 4300rpm, I think it has to do with the fuel but I'm not for sure BUT it don't do it all the time??? I know the car has more than that because when it don't do its thing I can rap it all the way to 5800rpm. The motor is fresh 15,000 and befor I got the car it was well taken care of....SO I AM LOST? Help

Thanks
