When i'm driving my car, if I baby the throttle it runs fine and if I floor it it runs fine. But if I give it between 1/4 and 1/2 throttle, it spits and sputters and I have no power. If I let off the gas and wait a second or two it will be fine. I dont know if it is a spark plug problem cause I havent changed them in about a year or so or if it a fuel problem. I replaced my fuel pump about a year ago. If anyone has any ideas I would really appreciate it cause im lost! Thanks!

 

bov flutter? what kind of bov do you have?

 

spark plugs is my guess...

 

+1 to that.
