See the upper man vac in picture. Appears to be a main vac source, I'd have to follow one of the other vac lines to its source. If the database is wrong, my bad.
When you take the line off of the vacum advance can you feel air comeing though it if you put your thumb over the end of the hose,? If not the line could be plug or a leak in it, some where. If that is not the problem ,Replace the distributer,
apply vacume to the vacume advance at the distributor.the diaphragm may not be working.also check to make sure the advance mechanism in the distributor is not siezed.the last thing you will have to check is when and if you vacuum ot the port on the carb that the hose connects to and at the correct time(throttle position)
code 34 means you are not getting any egr flow. find your egr valve and check to see if vacume hose is attached, if so follow the hose to the egr solenoid which should have that hose and a direct vac hose going to it. and an electrical connector. make sure all of these things are in place and not disconected or broken. the most likely cause is either a broken vacume hose or a clogged intake manifold.
Check vacum at brake booster if you have vacum there bad brake booster, if you don't follow vacum line check there, vacum line should go to intake, if you do have vacum replace vacum hose.
well ther should be a vacume diagram sticker under the hood if it is gone or wore off you can get a haynes manual for that specific car at advance or autozone for about 20 dollars and it will have a diagram in there
make sure your vacuum advance doesent have a slow leak, attach a spare piece of vac hose to the vac advance mod on the distrributor and s u c k on that hose., it should hold air and not leak make sure you dont have any other vacuum leaks. the vac mod on the tranny could have the same problem. open the jets on the carb a little by turning counterclockwise, you see the engine mellow out. theres two screws up under the front of the carb might need a rebuild, fuel filter could be half clogged. and then re time the engine..
you probably have a vacume leak leading to vacume advance to listen for a vacume leak take a piece of garden hose @3 ft long stick one end to ear and the other end arround the distributer cap with the enging running it will saund like a hiss if you hear it replace the hose. which you can get at any auto parts store
Do you have a Vac leak? easy way to find is to let run and open hood.. buy a can of starting fluid.. sprey around the Vac hoses and when the engine RPM picks up you have found your Vac leak.. hope it helps
