Hello all, I'm having a weird and frustrating issue with my 1985 2F FJ60 that I was hoping I could get assistance for.
A couple of weeks ago it was running fine and dandy, then one night on my return home from Taco Tuesday it started to pull and hesitate from 1500-2000 RPM intermittently. I first thought it was a fuel issue as it was acting like it was starving for fuel at these random moments, so I replaced the fuel pump with a new OEM one from @ToyotaMatt.
Well, I took the 'ole girl out for a ride around the block today as the weather has finally started to clear, and the issue still persists. I'm unsure as to how to proceed now as this has left me stumped and frustrated. I just want to be able to drive the 60 around with some peace of mind that it's running right.
What are some of the other items to check replace to diagnose this issue? Cracked/faulty intake manifold? Bad fuel filter? Carburetor? Vacuum leaks? The engine bay is mostly desmogged besides the carb and dizzy, so the EGR and air pump are gone. I also mention the intake/exhaust manifold because there's a loud squeak/chirp that seemingly comes from the manifolds at medium RPM/load.
Any and all help would be greatly appreciated!
