I have a 1998 honda accord v6 coupe, just lately it has been acting up. It will start up and then I can feel the revs droping down like it is going to bog out and then ill hit the gas to rev it up before it bogs out and it just dies this will happen 3-5 times before it will actually start it doesn't happen when the car is cold and it only happens some of the time once the car is running it runs perfectly fine I don't know please help
