    84 K5, manual tranny. Granny gear plus 3. 1st and 2nd are now ok, shift to 3rd and step on it and it stumbles until I pick up more speed then it smooths out. Bad wires? Cap?Rotor? Timing? Had the timing at 10 degrees before and put it back to 4 degrees and the stumbling that I had in 2nd gear is gone. Now 3rd is still a problem.
    Thanks!!
    It's FREEZING in South Korea! It's so cold that even the ice has ice!

    ?????? good question I have an 84k5 4spd just like you.I have my timing set @ 4 degrees & I have a stumble in 2nd gear when its close to red line I was goimg to try the timing at 10 degrees,but if it didn't work for you maybe I won't.
    I have all new plugs,wires,ect.I even have a brand new electronic dist. I have my choke wired completly open I don't know if that could cause the problem or not. I wish I could help you. Bruce

    I would replace the cap/rotor (cheap), spray the wires with some water or replace, inspect the plugs and the gaps, and put the timing into specs. Then go from there.
