Might be worth pulling the left-side valve cover to make sure 5 & 7 are getting good enough oil flow.
Also, with the VC off, you may get a better idea of just where the noise is coming from.

True, but why does it go to hell only when I pull it into gear (R or D)?

Is there a vac line to the 700R4?

'89 vert: bow won't release; top "stuck" in down position.

Pressing the button behind the driver's head rest has no effect, not even a "click".
Same issue when setting the parking brake and pressing the console button (yes, it's a 6-speed manual shift)....

The mast should not move easily unless broken from the gear inside the assembly, IMO.

I think replacing the antenna assy. in your '93 won't be a terrible job, like it was on my '88.

Indeed, if FP is too high it will cause rich running.

Pull, say, #1 spark plug to see if it shows rich running, just for verification.
