Many things can cause that. Either the fuel filter is clogged or the fuel pump isn’t pumping fuel and it won’t rev. Of those things, often the MAF sensors go bad and gets covered with dirt or goes out and then it doesn’t give the correct data to the computer. This results in the computer not spraying enough gas in the engine when it tries to rev it up. These are some of the things that you really want to check out first.
