Now you need to check that the actuators actually remain open. If the diaphragm in the actuator has a hole in it the valves may open briefly or not at all
Temperature test on a Catalytic ... that's a new one for me .... I wouldn't know if that is a good thing or not.

Here's a great thread on the SSV

No it opens closer to 4200 rpm but its not a set rpm amount it can vary on load while the APV opens at 6250 rpm
Coils can cause problems at any point.

Don't know what your budget is but I wouldn't go with the OEM coils .... go BHR

Coils are expensive ... OEM or Aftermarket ... so before we go spending your hard earned allowance lets try and find out what the problem is exactly.
I'm going to list some stuff and you are not going to like all of it ... but you need to be aware that a rotary engine with that much mileage on it is going to need work ... mostly likely.
/start list
- Coils .. common problem and OEM coils only last around 30-40k - how do test them .. people generally have misfire issues
- Clean the Maf sensor
- Clean the ESS sensor
- Catalytic convertors fail all the time on the 04 and 05 models ... very very VERY common problem and really expensive to repair
- Compression ... low compress is another very common problem ... getting a compression test done is cheap and will give you a good idea of how healthy your engine is.
- Air Filter dirty
You'll need a vacuum pump to check the actuators for the SSV .... hook up the vac pump to the actuator and make sure it stays open ....
Personally I would take the Upper Intake Manifold (UIM) off but not everyone does that.
happy searching and reading ...
