I am running out of things to replace and go over. One thing I will add is that before I replaced the variocam solenoid/actuator, the car would run perfect, but after I took it past 3,000 rpm it would idle bad since the variocam actuator would stick. but now it doesn't stick and the car always runs like crap below 1k rpm... why does the car still run so bad?

I would think that your issues with the EVAP system contribute to your stalling issues.
I am not schooled on all aspects of EVAP system operation but I do know it is constantly testing for vacuum integrity. It looks like a simple system but access to all the hoses and parts looks like a PITA.
If you are still throwing the P1341 code then something is still off with the timing.
If the car ran well below 3000 RPM before the actuator change out and now it does not. Then something is not right with the cam timing, the actuator, sensor or the DME/ECU.
Your timing code issue is a big issue perhaps you need a fresh set of eyes on the issue. Cam timing affects vacuum, fuel mileage, idle, power, and is most likely the cause of the miss fire codes.
I will have a friend who is also a car nut look at an issue when I am stumped just to get fresh eyes on the issue. Sometimes he sees something that I missed or just didn't see as set up wrong.
Another thing is in your posts you have mentioned that most of the SAI hoses were toast or not hooked up.
The hard starting at fill up.
The sticking actuator.
So it sounds like the car was not maintained well and that you have multiple issues in various systems.
Sorry I am not more help
