I'm sorry but that is random. Changing stuff when it doesn't need to be is a random action.

Logic path is:
1. Is it too tight or too loose
2. If no... stop

Regardless, at current, the cable wouldn't solve my current issue even if it'd idle properly after adjusting. With my foot on the gas at a 2k idle my AFR's are still 17+ I'm praying the new plugs fix that issue. At which point I assume I'll retain my normal rich/warm motor idle. We shall see though.

One of these days a fuel pressure test might be in order. Maybe next after the ignition components.

Ok, so after everything else has failed to attempt adjusting the cable is random? In that case I suppose I'll randomly change my oil in another 1,500 miles.

When all else fails one tends to attempt any last resorts.

......note taken Ben.

Attempting the cable was through process of elimination. Shoot, it worked for you why is it random for me to have tried it?

Ben, my fuel pressure is steady at 3 bar via fuel pressure gauge when the motor actually idles. dunno if that's what you mean by fuel pressure test.

Yah, that's basically what I meant by a fuel pressure test. That's not even close to right, is it fuel-pressure-testing-people? (I've never worked with a fuel pressure gauge ever in my life.)
Shouldn't his fuel pressure, at idle, be 3-bar minus maybe 0.7-bar? Shouldn't he be around 2.3-bar at idle with the vacuum line hooked up?

What does your fuel pressure gauge say when the fuel pump primes, but before cranking?

When you're idling, and you remove the vacuum line from the FPR, what fuel pressure do you see then?

Holy crap my plugs are here!!! I will install these and inform my findings. I will also check the exact number of fuel pressure. Iirc, it's at 38psi with the line connected. I dunno with the pump primed. I shall return in about 10min........

should be 3 bar/43psi(assuming stock ecu) with fuel vacuum crimped/pulled. I always just pinch mine.

I don't even pay attention to what it is with vacuum. I'd assume that depends on what your vacuum is!

10 minutes, 2 hours...same thing!

But Omfg!!! EXACTLY what I've been saying the whole goddamn time!!! I certainly needed new plugs no doubt but a MF boost leak!!!!!! Fukkin bitch! Who's yo daddy you car!?! I AM!!!!!!!!!!

Ben, I again owe credit to you! Had I not been futzing around at the FPR I'd have never heard this 2 pack a day weezin for air!!! I thought it was a few different things and took me a good 1.5hr out here in the rain but dammit, I found the leak!!! It was the nipple after the throttle plate. Iirc, I had it blocked off. The plug must have escaped. I could just hear the motor missing bad and as Soon as I put my finger on the hole? She smoothed right the F out like a 5am country lake!!!

AFR'S dropped back to their former rich postion, all seems well.

NOW!!!! The question will be is after I turn the o2 back on in the tune will she idle cold? THAT is the originating question of this thread. Supposedly the o2 was the culprit. Please dear boost gods lets put this war to sleep!!!
