Air in the ABS control module? I have read it is a bear to get air out of all the channels without activating the valves and pistons inside the module.

A camshaft position sensor caused those issues on my 850.

I am guessing crank position sensor.

Correct on washer breather hose. Can even see the metal clip in picture, look at yellow sticker and move left, follow the fender ridge down about two inches toward front of car.

My 94 did same thing, also with no codes, until the camshaft position sensor was replaced. It is a silver cylindrical disk just aft of the cap and rotor. Check for corrosion on the connector first. It may not be the issue but is simple to look at.

Try something easy first. Foot on brake, push the shifter while in park forward and then gently try to turn key.

Buy one from a MVS sponsor FCP. their part # 124622

I want to believe "it feels like it keeps 'turning over' for a split second after I've cut the juice." is causing the random misfire codes as each time you shut the car off you get a different cylinder. I second the clearing and wait to see what pops up first.

I may have stumbled on the reason for the wheel laced fluids. I recently put Fluid Film rust and corrosion protection on the surface face of the the rotor where the wheel makes contact with it. I now have the same spiral streaks.
