Hello all, I am new to the forum here and I have something that has me stumped. I have a 1982 4x4 with a 22r, running a weber 38/38 carburetor. Recently it has developed an intermittent miss that comes and goes, it is most apparent on acceleration and higher RPM. I though maybe it was crappy gas but that was 3 full tanks ago. The engine has less than 35k miles on it I am also running a 255 cam and just did a valve adjustment, new cap, and rotor. The spark plugs and wires have less than 15k on them and the weber carb is only 4 years old. The distributor was replaced and timing set a few months ago because the vacuum advance went out on the old one. The fuel pump was replaced 3 years ago along with the fule lines all the way back to the tank, I also dropped the tank and cleaned inside when this was done, fuel filter is new as well. Only thing I haven't done is rebuild the carburetor or replace the original factory ignition coil, I just wanted to see if anyone else has run into a similar problem that had some advice.
Thanks for any help.

 

Im having something like that in my 1987 4runner

 

ok, have you had an luck figuring it out? at this point I am leaning towards a fuel delivery issue.

 

Working on it. Its my current mission to solve this problem
