I just bought a 04 acura tl at 92,000 miles. The car is in great shape and engine still runs very strong except one minor problem. When i press on the gas pedal from 0-30 miles or 60+ miles car seems fine but from 30-50 miles i can feel the gas pedal vibrates a little. Plus when i press on the gas pedal medium speed ( like to maintain the currently speed) it vibrates a little too. I don't know if it's a problem with all honda and acura or it's it my car. Could it be the fuel injector or something else? Is it something i have to worry about? Does anyone have this problem too?
