Ok, sounds like you covered the basics with spark. I would check in this order; 1-Throttle position sensor, sometimes it wears out and you get poor signal back to computer, 2-clean MAF sensor, 3-check/clean IAT (intake air sensor). If this still doesn't help then I would check your fuel flow....but i'm thinking its your tps. Two screws will change that out quickly.

Well this could be in your timing. As cars get some miles on them the timing chain stretches therefore causing you car to lose alot of power.So you may want to have your timing set on this car. Also I had a taurus that had a bad torque converter, and it lost alot of power on hills and under loads, also when i gunned the gas pedal. so try the timing first. Hopefully you dont have a bad head gasket or a cracked head these symptoms you are describing are all signs of head gaskets or blown heads

Starts missing /large dead stop when accelerating

The missing while accelerating is likely due to ignition coils and/or spark plugs going bad. The missing while in park is a normal thing. The car has a rev limiter that will not allow the engine to rev to higher than 3000 RPM while in park.

Check for vacuum leaks. With the rpm difference that large it should be pretty easy to hear the vacuum leak hissing with the engine running.

There appears to be a thermal movement of choke mechanism that comes about once vehicle is warmed up. Check the chock connections, hot water pipe and linkages tight or clear.

'90 900 manual starts, stalls, and can't start again

The complete loss of oil suggests that you might have a piston problem!

First, check the compression on all cylinders; all values should be within a range of 10% from highest to lowest. Typical value about 140 psi.

One cause could be a blown piston or rings, allowing pressure into the crankcase, and blowing oil out of the filler pipe - very fine and barely visible, not spouting. You might feel the pressure pulses from the damaged or leaking cylinder.

If one cylinder has zero pressure, it's more than likely the cause of the problem. Do a wet compression test (pour a little oil into the cylinder immediately before connecting the compression tester - it usually seals any leaking rings for a little while) and if it holds pressure, that points to the rings; if no pressure again, that points to the piston.

Let us know the compression test results.
