My 1985 caravan runs for a few minutes then boggs down after a few minutes,my uncle says its an air sensor but im not so sure

Have you tried the idleing sensor or air intake sensor ? Not sure of proper names of them throttle body sensor

Could be plugged up catalityc converter.

do you have a MAF, mass air flow sensor ? it should be located right after the air cleaner filter before the throttle body . I have a 1987 buick grand national & it was running like yours, I ran into a mechanic online who sum it up with a detailed report, bottom line, REPLACE YOUR MAF !!!!!!!!!!!!! after doing things like you did, replacing everything but, the MAF was EXACTLY what It needed !!!!!!!!!!!!!

code p 0106 refers to manifold absolute pressure (MAP)sensor or barometric pressure (BARO ) sensor---range /performance problem====causes ---intake / exhaust leak---wiring --- MAP pr BARO sensor problems
intake leaks( vacuum leaks)can be purge vent leaks, transmission actuator leaks , dash vent controls vacuum leaks
exhaust could be cracked flex section of the exhaust pipe at the manifold

Clean your MAF (mass air flow sensor).

Google a Youtube video on how to do it.

You just need electrical parts cleaner or MAF cleaner.

Check spark plugs and ignition coils Im no expert tho

im pretty sure that the float adjustment is set wrong, if to high it will act as if truck is flooding out, and be very rich. if to low you will not get the power you need. readjust float level. make sure there is no dirt inside carburator. for adjustment turn screws way in and back out 1 and a half turns.start from there.

get to the real problem by having the fault codes read and fixing the revealed sensor problem

Ok, Try the maf sensor.

i would check that first and then the timeing.
