Thanks! I have not gotten that deep into it as it's been crazy busy. At first, I thought it may have done something horrible like jump time but the way it ran today for the first 10 minutes or so makes me think otherwise because it was silky smooth.

I will or may get deeper into it if the coil does not work. Apart from the engine, this is a spitting image of my 560SEL so I can always part it. It has many usable parts. It would be a crying shame because it's a quite clean.

I will disconnect the EHA valve and the computer in order to see what's going on.
