i have a 84 se. I tested the maf per the Mazda fsm and its in spec except for one check. with the flapper open it reads 2ohms and the tolerance is 0ohms. my issue is,after about 15min of either idling or driving the engine looses power and wants to die. if I exceed the 15min it dies completely. I thought it was in the ignition,but everything is in good order. I thought it was running hot,so I changed the tstat and flushed everything. the temps are normal.
