Vaillant GA92-100 Problem, driving me crazy!

[Chrisnbig]

I have a Vaillant GA92-100. It likes to turn on and off all the time, it heats the house and runs fine sometimes, but when it starts to turn itself on and off it does it up to 10-15 times in one minute.

So far I've done about everything I can think of and I am going crazy because I keep spending money and no results (Granted I have spent less than having a pro come trouble shoot)

I've replaced:
S8610u Ignition Control
The flame ignitor assembly (built in flame detector)
New Aquastat box
New thermostat (mainly because I just wanted a new one)
Checked most of all the wiring cant think of any other wiring to check.
I checked voltage on the gas valve that seemed normal
I jumped the t-tv to cancel out any bad thermostat wiring.

All to no avail, Its a long shot but maybe someone here might have a idea?
Here is a video of it doing what it does:

Thanks in advance.

How about the flame roll out switch?

How about the flame roll out switch?

That was actually the first thing I checked, forgot to mention it sorry. I jumped the rollout and the problem persists.

Unless it is actually having flame rollout?

How about the stack overheat switch, incoming gas pressure, aquastat differential, does the unit have Taco zone valves?

There is no zone valves, I haven't checked the stack over heat switch, is that the one that would need to be manually reset in order for it to fire back up? I'm just assuming gas pressure is ok. None of my other appliances have any problems, when its not having this problem the boiler runs great.

The aquastat I put in was set up how ever it came from the factory, High limit was 180*, don't know what low was. But if there is call for heat it turns back on at 160*..
