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?
