Just picked up my '92 400e (97K mi, all documented factory services, nearly perfect, $5500 on eBay!) in Albuquerque yesterday and drove it 400+ miles back to Phoenix. (25mpg!) **** I have a '90 300e that I thought was a great ride, now I am spoiled! WOW! Too bad it's for my wife!

I did notice a few minor glitches.

It idle, it seems to bounce up and down a bit, smooths out as soon as it hits 1K rpm. Just passed emissions, and tach doesn't quiver, so maybe motor mounts?

The oil pressure gauge just lays there at 0 until its at >1500 rpm. It stayed at 3 all day yesterday while running 80 in I-40. Oil level OK, changed 1K miles ago. Cause for worry? My 300e shows at least 1 even at idle.

Brakes seem to pulse slightly at low speed, mild braking. I looked at the pads while they were balancing the tires, fronts will need done relatively soon. Maybe a slightly warped rotor?

Anything specific I should watch for on this beast?
