alright so about 2 nights ago i have noticed this problem. when i take off or any time i am accelerating. it surges like its not getting fuel or something so i have been thinking fuel pump i just replaced the filter. but my fuel pump sounds the same as it always has. i dont know if it would change or not? and i have also noticed now that i have a small exhaust leak but i dont think it would make it do that either. all my info is in my sig. i have added new denso iridium plugs if that helps to but that just made my car more responsive once i put them in. so if you have any input or have had this problem your self send some info my way becuse i am lost right now. thanks.
