how do i do it. ive done numerous searches, but cannot find out how to exactly. ive read here and in the manual u need approx 0.6v closed and 4v fully opened.

i measured the signal cable (middle) when i disconnected the harness but from that side of things im getting battery 12v from the middle cable. from the TPS side i get nothing, obviously as ive disconnected the harness.. can someone help me adjust or check if my TPS is out of place?

cheers

tom9999 if ur car runs rich it may be a few different things. as long as its running rich its much safer than lean.

ok thanks heaps. one dude said its too rich and he said he was going to adjust the tps so yeah i didnt want him to just incase like you said safer to run richer than leaner.[i know skylines are meant to run rich]

tom9999 maybe also try replacing the O2 sensor and make sure the fuel pressure regulator vacuum hose is connected properly..

ive adjusted my TPS to 0.5v on my r32 and it has fixed my high idle problem.

      Starter motors used to use the weight of metal (magnets) to provide torque. Now they use (more) current instead. This. It's completely normal.

      So thing that had me stumped, but I think is OK....is that when it was up in the air, in neutral I had it running to bleed to coolant while I put the wheels back on. I noticed the rears were turning (slowly) which I'd never seen before 20250928_163512.mp4     Because there had been an issue with clutch slip due to pedal adjustment on the dyno, I assumed there was still and issue so spent some quality time upside down under the dash adjusting the pedal....but no matter what I did the wheels still turned in neutral. Even disconnected the master cylinder to pedal rod and same. In despair, I even removed the clutch slave so there was no chance of any preload causing it.....still happened. So either: 1. Something is not right in the bellhousing, or 2. Its a thing sometimes with cold, thick gearbox oil Internet says it might be 2, I hope so!

      OK, few more things sorted and it is ready for a shakedown on 10-Oct, with one weird thing. Changed the run in oil and filter for the good stuff. 8l came out, about 8.5 went in with filter so that looks all good. Changed the starter (again), this time for a brand new one, works good. Interesting that the Taaaarks one is shorter than factory but spins harder, I guess electronics have moved on a little in the last 30 years. Will be nice to have a bit of extra space under there. Put the timing cover back on, and noted where the cam gears were set as a record.  Will need to double check the timing but it is pretty close. Also put the coil pack cover and intake snorkel back on. Exhaust Inlet Changed the water out for coolant, bled up nicely. Removed the rear brake pads (well worn factory sumitomo ones!), gave the hardware a good clean and reassembled. I've put bendix XP on the back again because the price is excellent at $150 a set and they worked well on the V37. Front pads have plenty so no issue there
