'92 Probe won't run with MAF sensor connected

This car was shut off and wound not restart. We took it to a mechanic friend and he said it was the MAF sensor. He modified it to get the car running, but it idles rough and is sluggish on acceleration. We got 2 used ones from the junkyard and neither of them wil let it run. If you unplug the MAF it runs for about 1 1/2 minuites.

Another friend has a SOLUS and we scanned it. Got 4 different codes, 2 related to the MAF, 1 about the baro sensor, the other escapes me @ the moment. Any ideas????

what are the code #'s?

the codes were 8, 10, 14, 17.


8: Vane Air Flow (VAF) Sensor

10: Vane Air Temperature (VAT) Sensor

14: Barometric Pressure (BP) Sensor

17: Exhaust Gas Oxygen (EGO) Sensor - voltage does not change


Some notes: according to our Chilton manual the BP Sensor is _inside_ the computer ECM.

Also they (the driver & friend) was messing with the radio, trying to change it earlier on the day that the car quit. Any possibility that they could have got close to the ECM and knocked a wire loose or damaged the computer?

This car is driving us nuts BTW. Any help appreciated.

unplug the maf sensor, and jump the test leads to the fuel pump located by the fuel filter, if it runs then there is something wrong inside the maf sensor, i just fixed a problem identical to this.
