My car was working just fine until a couple days ago. I went to accelerate normally, not fast, at a stop light and it acted like it wasn't getting enough gas. I took my foot off the gas and tried to accelerate again and it went just fine. Now, a couple days later, when ever I want to accelerate I have to extremly slowly other wise it acts like it's not getting enough gas. What's wrong with it? PLEASE HELP!
