I think you HAD low fluid and bad cylinder(s), now I think you have either low fluid again, a sensor on a cylinder that was not seated quite right and came loose (saw this once) or a misadjustment/bad cylinder at the deck lid latch.
It's hard to say, I could be way off, but that's what I get from all of this. THe fact the lid won't latch right, even manually, is a dead give-away that you have something physically wrong with that latch.

The only guys I know that work on them and are GOOD at it, are in Florida and South Carolina. THey both travel to work on the cars, if you want me to contact them, PM me your phone number and I'll pass it on.
