Hey scott whenever i am driving under 2,000rpm my car works fine as soon as i demand more power going above 2000rpm it starts to cut in and out I've checked fuel and fuel filter also fuel lines and everything is okay, would you think the misfire is due to fuel injectors or timing? I've checked spark plugs and spark plug cables as well, maybe coils? what do you think? its a 4runner 1998 thanks bud!
first, pressure test the fuel pump. If not weak, try this viddeo
