Got a couple of issues that have started to bother me with my 33gtst

Only engine mods are cat back exhaust and pod filter

Problem 1 - On an incline when i start the car, the revs drop below 500rpm and it stalls. Start the car and the same again. When i rev the car it revs smoothly, but then drops to 500rpm and stalls. Move the car to flat ground and its fine

Problem 2 - which i think is the sparkplugs - on a hot day the car doesnt misfire at all, however on a cooler day or at night it misfires terribly

I have inspected the coils and i dont think its them, as on a 30 degree day it doesnt misfire

Im going to clean the aac valve to see if it fixes problem 1

If anyone can provide some insight that would be great

Cheers

J

what boost are you running?

The colder temperatures might be enough to cause a slight increase in boost, enough for your coils not to be able to cope, or forcing the ECU into R&R mode.

I had a similar problem with my car stalling but on any surface. No idea whether it was related, but I tightened my power steering belt (it was screeching for a few seconds on startup) and the problem has disappeared.

      Interesting, I've heard complete opposite on my end. Bit of a lottery I guess.

      Mistakes were made, my R34 Story

      Getting Dangerously close to being ready to go back in the car. Rockers in with clearance castings now (and a quick check with the USA for the torque settings for the larger custom bolts) Covers and ported FAST Manifold sitting on there. Not fully tightened down as there's some clearancing required for the water pump with the earlier LS1 water pump styles. Example of the clearancing needing to be done: The body has to be ground a little but I'm struggling finding an actual piece of it. The later variant of water pump resolves the issue as the manifold was designed around it. It only came on the VZ LS1 in Australia, it got a different pulley for Gen4 motors. (it also costs $450... vs... $0).

      Doing some height adjustment on front suspension on a v35 and noticed this. The passenger side looks correct. So wondering what's happened to the drivers side?

      Oh...I have the electric mirrors as well iirc ...they're in the same state as just about every other R31 door mirrors, with the 3 plastic screw towers broken/cracked in the plastic molding. All the interior is 'dry', so the mirror switches etc likely all work fine. Some pics below of the trimmer pieces ~ looks to me like previous owner, painted chrome finished trims with black paint ...ergo, the chrome underneath is likely a-ok... ...starts to look yukky posting stuff like this, how much did it cost in fuel on your last sortie up this way?...me just thinking aloud, borrow someone else's 4cyl to cut costs, come do your own pick'n'pull like before to save me some bother...hehe.. but whatever, I'll just earmark bits I know you want, because the way this is all panning out, I'll be able to retire the R31 from daily duty at long last, replacing it with a Subaru wagon I'm lining up in the wings...ergo, my attitude towards the donor pinny shell is starting to wane a bit, and I'm more than happy to help you out there... Like you say though, no rush...and I'll guarantee we won't be moving too far from this locale at any rate 😎
