Engine hesitates when warm.
1982 fj40 starts and idles fine. Engine hesitates at steady speeds when warm. It feels like fuel is being cut off and then turned back on very quick. It might happen 3 or 4 times per min at cruise speeds. I think I have some sort of vacuum leak. I replaced all vacuum lines but no help. Fuel psi and filter good. Many thanks, SlyBird
