After writing my last post I got thinking how nothing is adding up.
Going back to my original post that closing the door was messing with thing I went back to the ecu. Cleaned all the contacts. Rapped on the side of the ecu. No change.
Had a spare ecu that came with the car. Plugged that in. Fired right up. Settled into idle. Brought it up to temp and shut down.
Fired up again. Good idle, no hesitation.
Hopefully that was my problem.
Never fails to amaze me how something can go bad sitting in the shop.

78 280, possible black pearl
