Please help me. Sometimes when I'm sitting at a light or even driving down the street my engine will cease to respond to me pressing the accelerator. The engine runs at idle speed, but won't accelerate when I step on the gas. If I turn it off and back on, it usually works again, sometimes on the second or third try, but it works again. I replaced the in-tank pump, but that didn't seem to help, in fact, it made it worse. It has a new fuel filter, so that isn't the problem either. If you have any suggestions, I'd be more than happy to hear them! Thanks.
