Electrical problem
1993 Mazda 929 6 cyl Two Wheel Drive Automatic 150000 miles

Ihad the engine out of car, codes for sensors on crankase angle and positioning sensors keep returning when engine reinstalled. Change the distributor twice, changed the crank position sensor, changed the computer, and all the wiring harness was disconnected and unwrapped looking for a short that may be the cause of the sensors to light upon dash and also the idle at a stop light fluctuates so dramatically from 200 to 1400 up and down. This occurs sporadicallyAfter installing the new parts it acts up within a few hours.I have spent thousands of dollars trying to locate the problem, the mechanics are now unable to locate the problem and I am out of steam, patience, and money. You advised earlier to send out the ecm so I changed it for a new one, so what else could be causing this to happen. Please help I'm desperate !

Do you
have the same problem?
