ok, I have an 86 22re Runner, and its got a problem that I jsut cant figure out, (had it about 1 1/2 months now) it surges or 'bumps' on the highway (about 50-60mph) runs fine at idle, steady, @just under 1K, on an Sr5 tach.
I have done just about everything I can think of and found when I searched.
Air filter, Cap, rotor, wires, plugs (gapped them @.45 and .65) fuel filter, cleand out the throttle body, (that was pretty dirty, and it stoped the computer from going into 'limp mode' at stop lights) and I messed with the warm idle adjustment (from 1 turn to 2 1/2 turns). Also an did an O2 sensor, just for fun and sealed up all the exhust leaks.
I have tried to get codes from it when its warm and stone cold, nothing is showing up. I also did a cluch (needed it anyways) but it had no effect on this problem
It does have a slight miss (only audable at the tailpipe) and it has a little bit of a low end nock... but runs KILLER! even better after I gapped the plugs to .65! Its just gettin realy annoying....
