We tried to provoque the hesitation: WOT, partial throttle, hight revs etc. Nothing happened. I think we can ruie out the DME.
I did notice that while removing the DME after a 15-20 minutes drive it was warm. I figure this is normal?
Tomorow I will unplug O2 sensor, reinstall the black coil, test the AFM try and test or clean the ICV - WOT switch and throttle body. I will also visually check some rubber while I'm there.
Thanks,

I'd take the elbow off and visually inspect the TB. You can open the butterfly and look for any buildup inside the bore. I'd also make sure and do a really good once over on your vacuum lines. It still strikes me that you're getting unmetered air. When you say the car idles fine but does not drop when you pull the oil cap. I'd get your vacuum leaks sorted out then move forward. If you haven't made sure your vacuum connections are good you could chase your tail trying to find the problem IMO. Start with the easy/obvious problem and then dig deeper.
