Maybe idling rough? Not sure

[Sandst4rm]

Hey again guys, separate thread because it's sorta a new issue.

Now I have just done new vacuum line on the fuel pressure reg, new map sensor vac hose and all the other stuff in my resto thread.

Power seems fine revs and starts mint but I still don't know if the idle is right, feels rougher than I think it should and shakes a bit visually.

Is this just how they run?

I know it's an old engine so if that's the car then no worries

2 things l noticed? Engine mounts?
Those aic sensors are 2 different ones. I think the one with the pointy tip is the one for your tb.
Which one did you use?
The other one is for a vx vy.

It seems noisey to me?

Seems OK to me- you need to let the engine computer relearn its new component's operating parameters and reset the IAC- there instructions on how to do that on here somewhere..

Did you install the IAC with the tip retracted?

 

[Sandst4rm]

I tried all 3 of those IAC and runs the same on all of them, engine mounts are 2 months old man brand new.

Currently it is running on the original VP IAC valve sprayed with brake clean

Is noisy because it exits before the diff with 1 res and full 2.5 system pacemakers

If you look at number 5 coil on the lead cap you will see it arcing to one of the other leads.
It happens or is noticeable around 0.40 in the video.

Good find. Clearly visible at the 50 second point.

Guys if you look closely you'll actually see that's a shadow

Yep, specsavers it is!
