Just bought a 90Qs 20V with a "few" issues.

I have not owned one of these in a long while, but here are some ideas.

First and foremost, get the bentley manual.

See below

Could be many things, btu I'd check the air plumbing first. Never had a 
problem.

Senders know to go. But you need to do the usual diagnosis. Its a car.
Use a thermal gun to check to water temp, check thermostat operation, 
etc.

Senders known problems across the board.  If it does nto move, its 
probably the sender, but it could eb the guage. Check the wiring, 
segment, diagnose. Does it move at all?  They should probably run ~100 
deg (its centigrade)

Switch.  Can also be the front (driver's) master switch which the local 
switches daisy-chain through.

It should be much faster than your 4kqs, btu will feel
very anemic compared to today's cars, especially if you drive a monster.
Remember, it was mid 7s to 60. Fast for the day.  Econobox today. And 
they need to rev.

Broken cables or mis adjustment.  Its a car! Just like all the others.
