Believe in coincidence? My 90 GL's wiring harness suffered a  non-fire
meltdown. I replaced this harness with one from an 87. All went smoothly
and she fired right up. Test drive : Pulling into a steep climb, coming
out of my driveway at full throttle, no power! Put her back in the
driveway and checked my work......all ok. Long story short, I could have
wasted lots of time looking only into the recent harness job and/or
consequences of meltdown, but as I stood over the bay, revving the engine,
I noticed the intake boot, downstream of MAF, contracting and expanding
like an accordion. After some quick dismantling, I discovered the base of
the snorkel (made of something you might vent your clothes dryer with) had
colapsed and was almost completely restricted, just above the solid
plastic 90, behing the RR tail light. I replaced all this with more parts
from the boneyard and she runs great. Case and point of this story? Well,
not only is it something we should all periodically inspect, (2.1s need
all the air they can get)but it is a good lesson for those who do not
believe in conincidence...........
