My 82 FJ60 jerks or maybe stumbles is a better way to describe it, at cruising speed, as if it's not getting fuel. I've replaced fuel filter, fuel pump, rebuilt the carb, new plugs, checked the EGR valve, adjusted the timing, but nothing fixed the problem.

Any ideas?

 

Wow! We get the same kind of behavior out of our rebuilt 22R motor. Check out this thread
