Video update for you guys to hear how its idling at the moment

You may have a vac leak.

WE HAVE A WINNER
My mechanic who fitted the new coupler found the leak and will now work with him to set a date to fix it.

Okay so since I got the new Delphi coils, should I put them in?
We know it's a vacuum leak that's casing my idle issue and the current coils are fine so no need to replace them now?

Also, kind of a weird thought but I intend to flush the cooling system soon and I will use some wheel ramps to get better access to the bottom of the radiator. Would there be any issues draining it while having only the front elevated?

I wouldn't raise it to do the flush. I would hold on to the coils until the vac leak is sorted. Concentrate on one problem at a time.

Yeah I'm not doing the flush for a couple weeks so the Vac leak is first and foremost.
Just trying to plan how I want to do it.
How would you recommend getting under to flush the cooling system? I can get 2 sets of ramps to raise the whole car up instead of just the front

Why would you need to get underneath?

Don't I need to drain the radiator when I do the flushing?
Or am I missing something?

Yeah you undo the hose clamp and pull the hose off at the bottom. It will be easier to access it from the top with a long screw driver or a 1/4 ratchet and a heap of extensions.
