These symptoms sound very familiar. My 5spd is currently exhibiting very
similar issues. I have chased vacuum leaks, disconnected the OXS with no
definitive improvement. I do also have some issues with the instrument
cluster. When I turn the key off the oil psi gauge pegs to the right. When
running, the temp & gas gauges are often inop. I can usually rouse them
with a stout whack on the top of the dash. When I do so, the seatbelt
warning light comes on briefly.
I'd like to compare notes as we go. I have had some occasional issues in
the past with one of the reference sensors. A couple of years ago, it would
not start when it was really hot. I poured water down behind the driver's
side distributor to resolve that. I haven't done anything about that
because I don't drive the car often.
It's been kind of a part time pursuit for me because I usually don't drive
it much, but I would very much like to get it resolved.
