(VIDEO) Help! Replaced FPR line, and M42 still hesitates at idle

^Original thread with asking about the FPR line that goes to the throttle body, I replaced this but the car is still running strange.

I didn't touch the idle control valve, and it still hesitates but it stays constant. Has a bit of a rough idle, but it might be just me, car has been under the knife for a few weeks and might've forgot how it idled. Here's a video, if someone can help I'd be very grateful.

It sounds kind of weird, but every M42 I've heard has it's own unique sound.. that one kind of sounds like a motorcycle to me haha.. it looks like it's at about 750 RPM idle which is good.. how's it run under load? Also, try warming up the car to see if anything changes..

Seems very strange, but it never used to idle this way either. After a few seconds the very fluttering hesitation changes to the slight hesitation at about 1-2k rpm. I tried cleaning the ICV but still the same idle. Could spark plug gap cause such a hesitation? I just tightened to hand tight and left it be (lack of proper tools). Also on a side note, where does the vacuum hose that goes from the valve cover go to? I over thought this but could that be the issue?

[Nairb]

The valve cover hose goes to the LARGE nipple on the bottom of the throttle body.. hard to get a pic of it on the car, but it's not hard to find.

Also, make sure that you have that tiny-little hose running from your injectors to your throttle body.. I have actually had mine slip off somehow. Kind of a bitch to get back on if it's barely long enough, but it needs to pull that vacuum.

Red is from the valve cover

Yellow is from the throttle body nipple

Green is from the vacuum hose coming right under the intake manifold, which looks like a perfect fit for it.

If the valve cover is connected to the throttle body nipple, where does the hose outlined in green connect to?

Bump, somebody please help me with these damned vac lines!!

Valve cover to large nipple on TB. ICV to nipple on intake elbow.

Thanks KenC, just to be clear this is correct?
