My friend's '87 Runner w/ a 22RE is having a "stumbling" problem between 2000-2500 rpms. The truck will lurch like it's not getting enough gas. It idles smoothly and otherwise runs great. The plugs, wires, cap/rotor are all factory Toyota and fairly new. I thought the EGR valve might be the problem but have ruled it out since removing it and plugging the ports didn't make any difference. Any 22RE gurus got any ideas? <img src="/forums/images/graemlins/patriot.gif" alt="" />
