OK after a New MAF the car, she still wont run right.....

Attached is my diagnosis procedure from the bible, can you guys look and see if I'm missing something. I grabbed my posting from NEO, and Ill paste it here because this is exactly what happened before the car went ka-putz.....

So I'm on my 5 mins drive to work, but get sidetracked by some suped up new mustang, had Cobra wheels or something, sounded not-stock thats for sure.....So we rip one on the 417, those familiar with the east end, we went from the police station to jeanne d'arc where we exited, had a quick chat, and i went to work late driving the 5 mins back because we went 5 mins past lol.....

I parked the car and let it idle down like normal. This was at 1430 and i go to work until 2100. I leave work, after a really busy nite, so I'm slightly frustrated, then I go start the car. Seems fine, try to drive off...BAM 2500rpm chugging...After the intial chug, it begins idling at around 1800....wierd.....

MAF problem, still in the mall parking lot, I check my SAFC and its gettin 0Vs....thats not right.... Wires all connected, etc, so I unplug my SAFC (After reconnecting the MAF wire), same problem, check the wiring, its all intact, still connected....

I aint towin' the car again, so i figure I drive it limping home cause it's only 5 mins, and magically, about half way there I notice its idling at its usual 850 or so, so I give'r...Its all good..... Next day, dead again...where she remains, except this time with a new 330$+shipping MAF yay!

Now...I havent had any issues yet with this plug, and one would think by looking at it that its obvious. (Sorry, on have the camera on my RAZR so...) I posted in the Classified section for someone with the same plug I could buy to eliminate that. I already resoldered the entire ECCS C/U blue harness becuase the one I got with my engine was hacked...and also missing a MAF plug, see the classified post for info on that.... So sick and tired of problems...I picked fast and reliable, not cheap...but it aint reliable

Thank you so much

      R33 GTST Steering Rack (49001-19U05) Rebuild?

      I've never played with one, but I would expect that you are correct. That slot looks like it is intended to be used to unscrew the end, and the flats on the body would be better than grabbing it around the round bit with a pipe wrench. So, yeah, probably unscrews. You'll probably have to make a tool to drive in that slot.

      A bit late but A disk S13P fit over stock R32 GTR brakes, usually A disk front, O disk rear works.

      Or, the height of the release bearing is not correct for your combo. Start with the bleeding and checking the slave moves throughout its range when you press the pedal (2 person required), but it is possible for the height to be internally wrong too (box back off to measure.

      Yes, there's quite a few things that can go wrong during a clutch install. Very unlikely. I have a similar clutch. They (ACS) make good gear. No, it is not normal. It is possible that you just need to bleed the clutch slave. But the new clutch will also have a more aggressive actuation force/pressure, and so your old slave cylinder might be a bit leaky or otherwise compromised, and not up to the extra force required. Or the master cylinder, same.

      Hi...so a "development" here aswell The swap is "done" and car went "test drive" BUT it seems the clutch(maybe gearbox?) is a little bit sad? I bought this clutch kit https://justjap.com/products/xtreme-heavy-duty-organic-clutch-flywheel-kit-nissan-skyline-r31-r32-r33-push-type "Problem" is that the first gear is hard to put into and it seems that the clutch is not disengaged. It was not the problem with the old clutch...(or like sometime the first gear would not get as easy specialy when the fluid was cold) So? Can it be like...bad "install" or is the clutch wrong ((it should not have been) i done research to get the right one) Or is this "normal" with new clutch and needs to be break in?
