Hey guys i just got my dream car last week. Its a 91 nissan skyline gtst type m. Ive beem saving for over 8 years to get this car and im so excited i finally have it. Im looking forward to many years with it. 

Unfortunately today i filled up my gas tank with 91 octaine ethenol free gas for the 3rd time since ive owned it and after i left the gas staion everytime i come to a stop at a light or intersection my car will idle out and die. I can start it right back up but the ilde is way low like 300 to 400rpm.

Can anyone help? 

Im not sure if this is the right place to post this question. Feel free to tell me and i will move it to the correct place.

You in the US?  You need 93 octane for a start, otherwise it will ping, especially in hot weather.  But this should not cause it to stall.  They will run (idle) very happily on any normal fuel.

You need to look to the functioning and state of cleanliness of the idle control valve.  There are about 40099922774774661191919 threads on here about exactly the same problem.

Turbo cars generally need high octane fuel to avoid what is called "pinging" as a slang term for detonation or pre-ignition, which is very damaging to everything facing the combustion event.  Your 93 MON in the US is about the same as our 98 RON here in Oz.  The cars were designed/tuned to run on 100 RON in Japan.  Using lower octane fuel is a recipe for unhappiness.

When I suggested looking at existing threads, I meant, use google to search for your problem symptoms, and point google at this site.  You will be surprised what you can find.  Read, read, read.  Do not expect to get the answer handed to you in the first 2 minutes, because internet diagnose is fraught with wrongness.  We can give you suggestions as to what could be wrong, but it almost always turns out to be something different (and usually stupid).

      Yeah, it's getting like that, my daughter is coming over on Thursday to help me remove the bonnet so I can install the Carbuilders underbonnet stuff,  I might get her to give me a hand and remove the hardtop, maybe, because on really hot days the detachable hardtop helps the aircon keep the interior cool, the heat just punches straight through to rag top I also don't have enough hair for the "wind in the hair" experience, so there is that....LOL

      Jacks that fit under GTR lips that can reach the subframe?

      On BMWs what I do because I'm more confident that I can't instantly crush the pinch welds and do thousands of USD in chassis damage is use a set of rubber jacking pads designed to protect the chassis/plastic adapter and raise a corner of the car, place the aforementioned 2x12 inch wooden planks under a tire, drop the car, then this normally gives me enough clearance to get to the front central jack point. If you don't need it to be a ramp it only needs to be 1-1.5 feet long. On my R33 I do not trust the pinch welds to tolerate any of this so I drive up on the ramps. Before then when I had to get a new floor jack that no longer cleared the front lip I removed it to get enough clearance to put the jack under it. Once you're on the ramps once you simply never let the car down to the ground. It lives on the ramps or on jack stands.

      Nah. You need 2x taps for anything that you cannot pass the tap all the way through. And even then, there's a point in response to the above which I will come back to. The 2x taps are 1x tapered for starting, and 1x plug tap for working to the bottom of blind holes. That block's port is effectively a blind hole from the perspective of the tap. The tapered tap/tapered thread response. You don't ever leave a female hole tapered. They are supposed to be parallel, hence the wide section of a tapered tap being parallel, the existince of plug taps, etc. The male is tapered so that it will eventually get too fat for the female thread, and yes, there is some risk if the tapped length of the female hole doesn't offer enough threads, that it will not lock up very nicely. But you can always buzz off the extra length on the male thread, and the tape is very good at adding bulk to the joint.
