    Default code 34 map sensor and 83

    ok, i dont usually post anything needing help anymore since i seemed to have gotten the hang of obd1 systems. however this will be the 4th time that a code 34 has come up with this system in the past 5 years. so here are my questions:

    1: are the map sensors that bad that they go out this often?
    2: is there something else that could possibly be effecting the map sensor?
    3: is there an upgrade of any sorts so i can get rid of the map sensor and still stay out of default mode?
    4: what is a code 83 and how do i go about fixing it?

    94 sub 6inch lift 34inch bfg mt. massive rework project soon. the audio system hit 150.3db so now its time to rebuild and try for 155db. mudpuppy is also getting a new engine, rebuilt ifs, dual 500amp 15.1vdc alts, 5 5,000amp batts, ant the combined wattage with the new system should be close to 15,000watts. this is going to be a wild ride boy and girls.
