From: nucleus
if the wires on the 91 MAF sensor are totally sealed, you may find
it acceptable to insert a (straight) pin into each wire near the
connector,
to allow access for voltage measurement. if the wires are NOT totally
sealed, you may find it acceptable to "back probe" the connector pins
with (straight) pins for voltage measurement. respondent "Me" is
correct
about faulty MAF sensors, the MAF allows the ECM to calculate the
injector pulse width. if you ever have the need to see if the ECM is
sending a pulse to each injector, you can insert a "noid" light into
the
specific injector circuit (i once used an analog voltmeter to see the
pulse,
when diagnosing an engine that would not start).
does your 91 have the TPS (throttle position sensor)? if it does,
you
can check he TPS using the (straight) pin method, however, i would be
surprised if this is your problem.
can you give more details about the "stumbling" problem? does it
occur when you suddenly open the butterfly when NOT driving?
or does it occur only when you are accelerating (under load) while
going through the gears?
this thread assumes you have checked for constant fuel pressure to
the injectors (and that the fuel pump is NOT an issue).
would be interested in more details about your Consult device.

I just had a complete failure and now I hope to be able to determine
what was malfunctioning. The car started fine but then when i tried to
give it throttle it bogged down as if it were losing power and then i
got it to run again (roll started it) for about 1/4 mile with very
light throttle. it was idling no problem.I parked, went into the
grocery store for less than 5 minutes, came back out, car refused to
start. it cranked over strong but i never heard it fire. about three
times i heard a muffled kind of detonation like it was thinking about
starting but it never did. so i'm thinking that the coil might be the
culprit. or the fuel pump died even though it always tested fine.
comments/suggestions? thanks! rw
