Here's a video of it running to help explaining the issue, ill also point out now that the lanbda sensor isnt attached but that wouldnt affect it.

Anyone any ideas as to what could be wrong?
Did this just start randomly or after addition of mods, parts change etc? I emptied the coolant system when doing the manifold on my 180. After I filled her back up, I had the similar idling.. it started fine, then when it began to warm up after a few minutes the rough idling started.

It turned out I needed to bleed the system, air pockets in the system (ecu gets confused temp readings). Prob nothing to do with your prob thou.

I'd also double check all the vacuum piping to be sure nothing is loose or damaged.. could a number of things.. MAF could have shat itself also

PS: great idea adding video
